Add `bool` configuration parameter

[c-dilks]

Attempted in #346, and passed all CI checks; however, thread sanitizer finds a data race when this feature is actually used in #342:

// in FiducialFilter::Start:
o_enable_pcal_cuts = GetOptionScalar<bool>("enable_pcal_cuts")

causes

I'm not sure if this is a yaml-cpp problem or if #346 is incomplete; at the very least, this issue serves as documentation of the attempt...
