volare pdkpath feature

[dlmiles]

Description

The function is printing the fully-qualified-filesystem-path to the PDK (from inside the volare manage storage)

Feel free to pick a better name than pdkpath

The purpose of this is to push back into the tool the implementation details of how to resolve a full-qualified-PDK-path by anything built on top of it.

Proposal

The command represents what the output may look like when this feature is in use

#  This is printing the current active selected PDK
$ volare pdkpath
/home/user/.volare/sky130/versions/cd1748bb197f9b7af62a54507de6624e30363943

This is a feature request to have the volare tool resolve the current active PDK fully qualified directory.
This is so 3rd party tool and scripts do not need to know the implementation detail of how to resolve the active PDK or how the PDK is catalogued on the filesystem, that can be volare's function to manage.

It should confirm the directory exists, before returning it on STDOUT (allowing scripts to capture the value).

Nice to have features built on top, with additional arguments supplied
