Add CIRCUITPY_MESSAGE_COMPRESSION_LEVEL
to trade compile speed & flash size

Initially enable the faster mode on rp2040 and espressif, where there's
usually plenty of flash available (these advanced techniques save hundreds
to thousands of bytes, which is important on a lot of old samd21 boards
but is a drop in the lake of a 4MB flash chip)

**CircuitPython** is a *beginner friendly*, open source version of Python for tiny, inexpensive
computers called microcontrollers.

This package contains the "stubs", or type definitions for CircuitPython.  With some advanced
editors and other tools, this information can be identify TypeErrors, AttributeErrors, and other
problems before you deploy your code to a device and can even help autocomplete your code.
