0.20.3

Bug fixes

• [build] Fix macOS distro download filename. Now it has proper .dmg
  extension. (#1198)
• [core] Fix opening projects saved prior to 0.20.0 with some pins explicitly
  bound to Never. Notably, the bug led to a transpilation error when using
  digital-output from own xod/core fork. (#1207)
• [core] Fix untitled outputs name assignment for C++. Previously, all
  untitled outputs got name output_OUT. Now they are output_OUT1,
  output_OUT2, and so on. (#1204)
• [core] Fix C++ generation from generic nodes containing
  not-implemented-in-xod which previously was silently failing. (#1225)
• [ide] Minimize performance regression in 0.20.x caused by generics resolution
  (#1213, #1214)
• [ide] Fix occasional [Object object] errors when deploying. Now they are
  still there but formatted properly. (#1203)
• [ide] Format transpilation errors that previously appeared as cryptic
  objects. (#1230)
• [ide] Fix uncaught error handling. Now they pop up as a regular error for
  easier reporting. (#1230)
• [ide] Fix canceling when opening a project. Previously it broke the current
  project (#1202)
