Add IVSCC analysis function labnotebook entries to the documentation

[t-b]

We already have the table at https://alleninstitute.github.io/MIES/file/_m_i_e_s___analysis_functions___patch_seq_8ipf.html but this is more for MIES developers as it uses IP constant names.

For use in e.g. SweepFormula it's nicer if we would have a list of values and descriptions with the real name (starting with USER...).

Extracting that could be a bit tricky. One idea would be to search for all occurences of CreateAnaFuncLBNKey in MIES_AnalysisFunctions_PatchSeq.ipf and then generate a table from that, similiar to GenerateAnalysisFunctionTable.

If that is done we should also refer to it from the labnotebook operation description in SweepFormula.rst.
