[WIP] Adding PnR test and 'small' config for faster testing

[gatecat]

This requires https://gitlab.lip6.fr/vlsi-eda/coriolis/-/merge_requests/13 on the coriolis side.

Issues:

• Grid alignment problems?

• Coriolis currently segfaults; possibly a problem with the above 'oeb' patch but I need to investigate

Maybe I should change something on the computation of the routing gauges or so. I compute them out of the design rules. Checked my history and I don't see anything recently in these computations though.

[FatsieFS]

After further investigation it is seen that the li (e.g. first metal layer) is not marked anymore as CRL.RoutingLayerGauge.PinOnly but but as CRL.RoutingLayerGauge.Default. Need to check how that comes.

[FatsieFS]

Fixes should be available in #3 Not fully tested as I have broken setup ATM.

Merged; not yet DRC clean but basic PnR now working.
