Ignore timestamps

[perigoso]

Footprints contain a timestamp field, kicad uses this to keep track of modifications, this is not relevant for a versioned library, we want to set it to 0 for cleanness, a check and a pre-commit might be something we want to implement later.

For now this is a regex to find and replace said timestamps.
's/tstamp [a-zA-z0-9-]{36}/tstamp 00000000-0000-0000-0000-000000000000/g;t;d'

SInce we are automating it, we might as well set it to the date of the last commit.

hm, not a bad idea, but that would lead to a lot of changes every commit, perhaps at release with the release script, also not sure exactly how the timestamp is computed, is it even is just a timestamp

Someone mentioned that the tstamp field might not be mandatory, we can test that
