Compatibility and MCS tracking updates

This release contains the following major updates:

• Updated various syntax and advection function to work with new version of Python packages (#79)
• Updated MCS movement calculations, including direction and speed filtering (#84)
• Added capability to track convective cells with composite (2D) reflectivity input (#86)
• Added new and updated existing analysis notebooks and plotting scripts

MCS tracking updates

This release contains the following major cumulative updates in the past several months:

• Added simplified robust MCS identification based on precipitation feature and example configs for DYAMOND data
• Added new MCS analysis notebooks and a gallery
• Updated Tb + radar3D MCS tracking codes to be more flexible with inputs
• Various bug fixes

Sub-minute tracking support

Added sub-minute tracking support on all feature tracking.

• The intermediate and final pixel-level mask files now have seconds in the filenames (e.g., yyyymmdd_hhmmss).
• Analysis and visualization codes have been updated to work with the new files.
• Added MCS tracking using collocated Tb + 3D radar reflectivity + precipitation.
• Added generic 2D feature tracking with two methods to define objects.
