Initial work to support curv (#578)

* Initial work to support curv

* Correct the initial code file location

* Preview and stl mvp working

* Prepare changes for review and preview build

* Run curv inside of /tmp

When exporting an stl it writes temporary files which is not allowed
when deployed to aws unless it's in temp.

* Lock in specific curv commit for reproducible builds

see: https://discord.com/channels/412182089279209474/886321278821216277/912507472441401385

* Add curv to backend schema

* Frontend changes to accommodate curv deploy

* Use vcount instead of vsize, as it's independant of geometry size,

This is good for CadHub usecase where we don't know anything about the
user's project

* Final tweaks for deploy

virtual screen size does matter,and curv is a little more memory hungry
than the other functions

* Format project
