these plugins is a subset of lv2

- they use json instead of ttl
- the features are limited ?
- some features and implimentations may not map 1:1 with lv2
- some features can be omitted or skipped, like log functionality
- experimental

also:
- internally they're lv2 plugins, unmodified ?
  - maybe they have some wrapper code, such as jet_wrap.h ?
  - but overall code and structure is unchanged,
    apart from patching for conversion if needed
- plugins should be listed somewhere like plug_build
- plugins should have saved build system and probabably os/system images (VM?)
  with patches to rebuild them again if needed, or validate;
  this should include all software needed to build a plugin, including compilers, libraries etc
