Jannocoalesce minor adjustments

[nevrome]

As suggested:

• moved -- no changes and -- copied to logDebug
• added reporting for mismatches, so targets that are not found in the source
• renamed --stripIdSuffix to --stripIdRegex
• added Uses POSIX Extended regular expressions. to the documentation of -stripIdRegex

The rest are cosmetic changes to make code and output more consistent with other parts of trident.

Here's how the output can look now:

$ trident jannocoalesce -s ../../community-archive/2021_CarlhoffNature/2021_CarlhoffNature.janno -t 2021_CarlhoffNature.janno --stripIdRegex "_SG_MNT" --debug
trident v1.4.1.0 for poseidon v2.5.0, v2.6.0, v2.7.0, v2.7.1

I think we should slowly stop to talk about "individuals" when we refer to .janno rows. This will be a long and slow process, but we should to become more clear in the terminology here.
