Deareis

- Added clickable hyperlinks to the `About` window.
- Added the ability to subtract the impedance of a fitted circuit in the `Subtract impedance` window by choosing an existing fit result.
- Updated the `Spectrum` combo in the `Subtract impedance` window to only show other data sets with the same number of points and matching frequencies as the active data set.
- Updated the `Average of multiple data sets` window to only show data sets with the same number of points and matching frequencies as the first data set that is chosen.
- Updated how LaTeX tables are generated when copying, e.g., fitted parameter tables.
- Fixed the BHT method (DRT analysis) so that it works properly when `num_procs` is set to greater than one and NumPy is using OpenBLAS.

- Added support for calculating the distribution of relaxation times using the `m(RQ)fit` method.
- Added support (including a keybinding) for loading a simulated spectrum as a data set.
- Added alternative forms of outputting circuit diagrams as SVG without terminal labels or any labels at all.
- Updated DearPyGui version requirement to 1.7.3.
- Updated `DRT analysis` tab to only show settings relevant to the currently chosen method.
- Updated how the `utility.format_number` function handles the `numpy.nan` value.
- Updated how the y-axis limits of DRT plots are automatically adjusted.
- Updated tooltips.
- Fixed a bug that prevented choosing to use anything but the complex data when performing a DRT analysis using the TR-RBF method.
- Fixed a bug that was triggered by having too few unmasked data points when performing Kramers-Kronig tests.

- Fixed bugs that caused the toggling of a plottable series (e.g., a data set or a Kramers-Kronig test result) in the `Plotting` tab to apply the change to the wrong plot under certain circumstances.
- Fixed bugs that caused a failure to properly adjust the axis limits in cases where the difference between the maximum and minimum values being plotted was zero or all values were zero.

- Added the 3-sigma CI series to the legends of DRT plots.
- Updated the order that the mean and 3-sigma CI series are plotted in DRT plots.
- Updated labels of plotted series in the DRT plots.
- Updated the 3-sigma CI series to use the same alpha value in the `Plotting` tab as in the `DRT analysis` tab.
A manual refresh of the plot is required for changes to take effect.
- Updated labels in the `DRT plots` section of the appearance settings window.

- Updated API documentation.

- Added the ability to copy circuit diagrams to the clipboard as SVG from the `Fitting` and `Simulation` tabs.
- Updated to use version 3.1.0 of `pyimpspec`, which resulted in the following changes:
- Added `Circuit.to_drawing` method for drawing circuit diagrams using the `schemdraw` package.
- Added support for using the `cvxpy` package as an optional solver in DRT calculations (TR-RBF method only).
- Added `cvxpy` as an optional dependency.
- Added `CircuitBuilder.__iadd__` method so that the `+=` operator can be used instead of the `CircuitBuilder.add` method.
- Updated `Element.set_label`, `Element.set_fixed`, `Element.set_lower_limit`, and `Element.set_upper_limit` methods to return the element so that the calls can be chained (e.g., `Resistor(R=50).set_label("ct").set_fixed("R", True)`).
- Updated the default terminal labels used in circuit diagrams.
- Updated the label of a terminal node in the circuit editor.
- Fixed a bug that prevented the lambda value input field from being disabled under certain circumstances when switching to the BHT method.
- Fixed a bug that prevented the "Copy output..." action in the command palette from working in the `DRT analysis` tab.
- Updated the minimum version for a dependency.
- Pinned Dear PyGui at version 1.6.2 until the automatic adjustment of axis limits in plots can be made to work properly with version 1.7.0.
