Digital temperature readout support

[AlexandreRouma]

I'm interested in accessing the ECP5's built-in temperature sensor (https://www.latticesemi.com/view_document?document_id=50468 page 9 to 12).

Is there anything I can do to help reverse engineer this feature so it can be included as a primitive?

The DTR primitive should be supported already, is there any problem you're having with it?

I see, I'll try it.

I opened the issue because it's not listed in the supported feature list and searching for the word "DTR" over the entire repo only gave a few results in the fuzzer.

I'll test it and close the issue if it works 👍
