Review and finalize support for TMC arrays

[nthallen]

An abortive start to genui changes is stashed on my laptop

• genui (from .genui to .cdf)
• edf2ext (from .cdf to ext/jsonext)
• csv2mat.m (from .csv to .mat)
• data_fields (from json)

I think the idea was to add array notation to the column headings in the csv file. genui would require explicit array indices, e.g. R[0:17]. The extraction would then have column headings of R[0], R[1], ...

I feel like I have already done some of this for HCHO BCtr data. That of course is under QNX.

No, BCtr data extraction required a custom procedure
