v0.5.6

This is a minor release that contains an experimental new feature and a number of enhancements, clean-up and bug fixes, which pave the way for the next major release.

New feature

• (beta) Allow interpolating CTD data in calibration (#464)
  • Interpolation currently allowed along the ping_time dimension (the "stationary" case) and across latitude and longitude (the "mobile" case).
  • This mechanism is enabled via a new EnvParams class at input of calibration functions.

Enhancements

• Make visualize module fully optional with matplotlib, cmocean being optional dependency (#526, #559)
• Set range entries with no backscatter data to NaN in output of echodata.compute_range() (#547) and still allows quick visualization (#555)
• Add codespell GitHub action to ensure correct spellings of words (#557)
• Allow sonar_model="EA640" for open_raw (before it had to be "EK80") (#539)

Bug fixes

• Allow using sonar_model="EA640" (#538, #539)
• Allow flexible and empty environment variables in EA640/EK80 files (#537)
• Docstring overhaul and fix bugs in utils.uwa (#525)
