WISH: parallel::detectCores() -> parallelly::availableCores()

[HenrikBengtsson]

readTrackMateXML() parallelizes on all hardware CPU cores by default:

Using parallel::detectCores() is problematic for many reasons. I explain why in my 'Please Avoid detectCores() in your R Packages' 2022-12-05 blog post. The simplest fix is to address most of the problems is to replace it with parallelly::availableCores().

FWIW, availableCores() is also agile to _R_CHECK_LIMIT_CORES_, so you can replace all of:

with

numCores <- parallelly::availableCores()

You convinced me. Now added.
