Create standalone conda package for library

The CAEN HV Wrapper Library was being bundled as a vendor lib here: https://gitlab.esss.lu.se/e3/recipes/CAENHVAsyn-recipe/-/tree/aebf565883291d17613eabcb05b88998ff0c0431/src/support

This should instead be packaged standalone, where it does not need to depend on EPICS. This will then allow the caenhvasyn conda package to depend on this package.

I have not tested this packaging with the downstream module, as I do not have access to any IOC needing it. But if the previous bundling worked, I assume the library will work without any other flags for relocation of the binary. The first real test will have to be made by WP12 later on when the conda design is replaced - FYI @caissarogue and @douglasaraujo.

I downloaded the tar-ball from CAEN's website (https://www.caen.it/products/caen-hv-wrapper-library/). The license specifies:
