Hum, the fastavro dependencies is getting more complicated:

• We have to use <=1.6.0 as higher versions are not compatible with schemas sent by the telescope
• only version >= 1.8.2 are compatible with the latest Cython version (3).

So if we want to keep using 1.6.0, we need to use Cython<3 and a build isolation... But this cannot be specified from the requirements.txt since the latest pip upgrade 😭
