Add Entraining CAPE (ECAPE)

[dcamron]

What should we add?

Add calculation for CAPE with considerations for entrainment derived from profile. References below for examples, explanation, and an analytical implementation.

@citylikeamradio do you have any interest in incorporating your work on ecape into MetPy? Wonderful work! (also hello, sorry for the ping out of nowhere 😅)

Reference

• AMS pub with data/code available
• citylikeamradio/ecape Python implementation with Pint+MetPy backbone

I'd love to contribute this! I'll work towards a PR ~01 Oct.

Another recent ECAPE implementation by Amelia Urquhart can be used as an additional reference on adding ECAPE and its associated parcel path/profile to MetPy (currently subject to verification).
