Move msgs in EcalProcessFilter to logging system

[tvami]

I am updating ldmx-sw, here are the details.

What are the issues that this addresses?

This resolves #1250

Check List

• I successfully compiled ldmx-sw with my developments

• I ran my developments and the following shows that they are successful.

Running

ldmx fire ldmx-sw/.github/validation_samples/ecal_pn/config.py

Now the

[ EcalProcessFilter ]: (event nb) Brem photon produced (some number of) particle via biasWrapper(photonNuclear) process.

are not printed out by default.

• I attached any sub-module related changes to this PR.

N/A

[tvami]

I also expect the log diff tests to fail with this

[bryngemark]

Really great, thanks for following up on this @tvami!

[bryngemark]

indeed the log diff is (except a few time stamps from configuration printouts) an ecal printout for each event. @tomeichlersmith @EinarElen thoughts on this, should the CI use logs at debug level to catch any differences?

[EinarElen]

Seems reasonable to me!

[tvami]

should the CI use logs at debug level to catch any differences?

I agree with this! It should be for all the tests, so beyond this PR, maybe we should just made its own issue for this?
