Further update linearize function
Use ip_isr's maskAndInterpDefect function

Delete local maskDefect function in favor of using the (essentially
identical) maskAndInterpDefect function in ip_isr's isrTask.py.
Use doDefect config clause when calling maskAndInterpDefect.
Set doDefect config default to True.
Wrap defect masking in a try/except statement

Likely a temporary fix: currently daf_butlerUtils raises a
RuntimeError if the given ccd has no defects so is not listed
in the registry.
Add missing date fields to bias and dark profiles in HscMapper.paf
Make defaults True for doBias and doDark
Fix "no defects found" warning message
