Xrscipy

Added

- `signal.extra.psd` is now available as `signal.welch` (as in `scipy`)

Changed

- Move `other.signal` into `signal` and `signal.extra` to better mirror `scipy`'s namespace (thanks smartass101)
- Remove `urllib` dependency (not relevant anymore)

Fixed

- Fix publishing CI

Changed

- Update docs

Fixed

- Fix pypi pipeline

Fixed

- Fix publishing CI

Changed

- Refactor some inner functions in `fft, fftpack`
- Bump minimum python version to 3.10 to support pipes `|` in typing.
- Change arg `a` to `x` in scipy.fftpack to match the scipy signature
- Add package to pipy

Fixed

- Correctly rename `shape` to `s` in the docs for `fft`

Added

- Add a changelog

- Add `poetry`
- Add several typing hints

Changed

- Turn the travis CI into a github CI
- Update the README
- Move several doc files into python docstrings
- Bump the minimum version of python to `3.9`. Also bump the requirements for `scipy` and `xarray`. If those are too restrictive, we may broaden them later.
- Refactor docs
- `xrscipy.fft` now mirrors `scipy.fft` rather than `numpy.fft`
- Replace custom documentation parsed by tweaked `docstring_parser` module
- Move `xrscipy.signal` to `xrscipy.other.signal`

Fixed

- Fix `fft, fftpack, integrate` utests and modules

Removed

- Remove the `interpolate` module, which is now supported natively by `xarray`

Initial release. This is the "old" version.
