This release includes a number of important performance enhancements, bug fixes, and under-the-hood refactoring to improve code readability.

Enhancements

• Full refactor of the functionality to directly storing parsed data to zarr before set_groups_* (#1185, #1218, #1070)
  • This avoids memory expansion during NaN padding across channel
• Improve compute_MVBS using flox (#1124)
• Revive and improve compute_NASC using flox (#1167)
• Refactor AZFP XML parser
  • Improved XML parsing by using xml.etree.ElementTree to be consistent with other XML parsers in echopype (#1135)
  • Parse more parameters and store in the resulting EchoData objects (#1135)
  • Add partial support for AZFP multiple phase settings (#1182)
• Overhaul AZFP Environment group
  • Set mandatory variables not in data to NaN (sounds_speed_indicative, absorption_indicative) (#1226)
  • Parse and store AZFP pressure data when exist (#1189, #1226)
• Add utils.misc.depth_from_pressure function for converting pressure to depth (#1207)
• Remove unused mechanism to selectively parse some EK datagrams (#1214)
• Enhancements of EchoData.update_platform method
  • Factor out utility functions to a submodule (#1209)
  • Auto-assign timestamp for fixed-location external data using first ping_time(#1196)
• Add support for consolidate subpackage functions to accept both in-memory or stored datasets (#1216) [NOT MERGED]

Bug fixes

• Fix EchoData.to_zarr encoding (#1128)
  • Eliminate preferred chunks
  • Ensuring chunk alignment and encoding only when handling dask arrays
• Fix scaling bugs in compute_NASC (#1167)
• Fix UnicodeDecodeError for ES60 files (#1215)
• Handle missing receiver_sampling_frequency for EK80 data (#1219)

Infrastructure and refactoring
