AntoineTUE/spexread: v0.2.2

Spexread is a Python package for reading Princeton Instruments SPE files created either with LightField (v3.0) or WinSpec (v2.x). This release mainly involves small bug-fixes and adds more tests to the test suite. Full Changelog: https://github.com/AntoineTUE/spexread/compare/v0.2.1...v0.2.2 Fixes: Files stored with LightField without FrameTrack metadata should now read correctly instead of raising an exception. Files without any wavelength calibration (i.e. calibration missing due to conversion of SPE2.X to SPE3.0) should no longer raise an exception.
