parterre 0.4.0: new names

parterre is now the official firmware name: versions are parterre-X.Y.Z (were og-X.Y.Z) and the firmware files are parterre-0.4.0-.uf2.

Lua calls renamed (the old og_* names are gone; update scripts that used them):

• parterre's own: pt_set_mode, pt_led, pt_keypads
• greenhouse's tools: gh_mem, gh_key, gh_mirror, gh_dump_file, gh_rename_file, gh_board, gh_midi_monitor, gh_midi_counts

Use greenhouse from greenhouse.vfmod.com (reload it once): older copies don't know the new names or files.

Updating keeps your scripts (the file system stays where it was since og-0.3.7). Tested on the Open Grid kit (RP2040-Zero) and a Seeed XIAO RP2040.

The firmware's grid hardware now sits behind a small board layer, the groundwork for builds for monome's grids. parterre is unofficial firmware, not made or supported by monome.

Full Changelog: v0.3.16...v0.4.0
