[FEATURE] compressed fab outputs should not keep source dirs

[oliv3r]

While useful to retain the source files when compression of fab outputs is used, it is not needed in regular cases, also we can just unzip the compressed archives. As such, an option just as keep_temporal_files would be useful to be able to set to remove temporary files, having a cleaner output result.

import:
- file: 'JLCPCB'
  definitions:
    _KIBOT_MANF_DIR: 'output/fab/JLCPCB'
    _KIBOT_POS_PRE_TRANSFORM: '[''_kicost_rename'', ''_rot_footprint'']'

The above patch moves the files.
Note that now the BoM and Position aren't part of the ZIP file. This is because you must upload them separately.

@set-soft makes sense, aren't the BOM and Position files used by the assembly service only anyway? And I suppose you mean 'need to be uploaded to jlpcb assembly service separately anyway'?

[set-soft]

When you use JLCPCB you must upload the generated .ZIP first and then the BOM and CPL files. You need them separated. I recently found it while doing some adjusts to the rotation filters.

Also note that the other manufacturer outputs doesn't generate BoM and position. So you currently get the same for all, the ZIP contains the gerbers and drill outputs. In the JLCPCB case they offer a "free" PCBA service, so this is really popular and we generate the files, but again separately because they are uploaded separrately.
