See inline code comments for more details regarding the reasoning

    Avoids a bug in VS2017 where the call_once flag is not zero
    initialized but dynamically initialized despite its constructor
    being marked constexpr. This leaves the singleton
    initialization open to intialization ordering problems.

    A local static variables avoids the ordering problem and are
    guarateed to be threadsafe in C++ 11.

This was a behavior introduced in #22425 to solve a problem with data
that wasn't being binned during the processing step. This changes it to
rebin only if it hadn't been during the processing.

The version=1 file parsing assumed that there were more column labels
than values in a given row. This caused a segfault when reading past the
end of a vector. The code now checks for the values and labels to have
compatible lengths for each row and reports mismatch to the user. There
are also several changes in what particular exceptions are thrown
elsewhere in the algorithm.

Move the implementation of V3D operators to the header. This results in
a significant speed up in V3D operators.

Converts a data value in a given range to an RGBA value

- Replace the '*=' operator by CreateSingleWorkspace & Multiply
algorithm to remove the extra logging.
- Handle the output of ExtractMask as named tuple, don't unpack. Just to
be future proof.
- Add some unit tests.
