If "type" is "logical" cast according to "as.logical()" logic

[trevorld]

• instead of Python's bool() logic (everything but "" is TRUE instead use R's as.logical()'s logic)
• write a custom function in our Python code and use that as our "type"

• @Lain-inrae although #37 hasn't been supported, casting to the "logical" type now follows R's logic instead of Python's logic.
• Doesn't seem to be quite what you wanted with a custom bool type but perhaps closer than before. "T", "True", "TRUE", "true", "F", "False", "FALSE", "false" (but not "0" / "1") now cast to "reasonable" values.

parser <- ArgumentParser(prog='PROG')
parser$add_argument('-p', type="logical", action="append", help="a list of booleans")
args <- strsplit("-p T -p F -p True -p False -p 1 -p 0 -p badValue", " ")[[1]]
parser$parse_args(args)

[1]  TRUE FALSE  TRUE FALSE    NA    NA    NA

Thanks that's great!
