Lasertram

This release serves to document the complete migration of the backend of `LaserTRAM-DB` to using the `lasertram` package.

major changes
- backend migration to `lasertram` package: https://jlubbersgeo.github.io/lasertram/
- removal of LaserTRAM profiler
- Incorporation of "record and next" and "skip to next" button
- Better statistics output for calibration standard
- Incorporation of internal and external error on concentrations

minor changes
- changed up some fonts and colors
- added a loading spinner for when data are loaded into the dashboard so user better knows it's loading

This release deals with fixing a couple bugs with the selection of the internal standard in that if the internal standard was near the end of the analyte list it was not selecting the proper column of data. This propagated through to the output from LaserTRAM. This has now been fixed and all data are exported as they are intended to be exported.

This release signifies a few changes in LaserTRAM-DB:

- The incorporation of datetime data into the sample metadata such that drift correction determinations are done using that
- specific yml files for MacOS and Windows installs
- The creation of a .exe file for Windows that runs the dashboard without having to do any scripting.

:bug: Bug Fixes

- fixed indexing issue in `despike_data`

:books: Documentation

- added more coverage in tests to now include `get_secondary_standard_accuracies` and `despike_data`

:books: Documentation

- added `lasertram.__version__`

:tada:

- changed naming of all functions that refer to standards for consistency
- Any attribute or method that references an internal standard uses `int_std`
- Any attribute or method that references the calibration standard uses `calibration_std`
