Update jana4ml4fpga to handle multiple evio file sources

[cissieAB]

A placeholder for jana4ml4fpga changes.

Now the cdaq plugin is using JEventSource with JANA default topology. jana4ml4fpga aims to a 2-queue based topology and it does not rely on JEventSource but JBlockedEventSource.

Commits:

Cosmetic changes

• [x] Add links to EVIO/CODA documents
• [x] Some cleanup, like remove CDAQfile repo, as long as deprecated_CDAQfile is there.

Major changes: update EVIOBlockedEventFileSource to handle multiple evio files

• [x] see above description
