Automunge

- a backward compatibility breaking rollout for the bins and bsor transforms
- wanted to get this out quickly before get too many users
- replacement of the standard deviation bins with the new versions rolled out in 4.76
- which is improved as accepts a parameter for bincount
- only slightly different in column header suffix encodings with integers which generalizes better

- new report populated and returned in postprocess_dict as a direct map from input columns to returned columns
- i.e. as a dictionary with keys of input column headers and entries of a list of returned column headers derived from that input column
- available as postproces_dict['column_map']
- excludes returned columns consolidated as part of a dimensionality reduction
- includes label columns
- this information was already available but now is more directly accessible
- also corrected MLinfilltype of datetime meta transforms from exclude to numeric

- new transforms for aggregating standard deviation bins with custom bincount
- (prior versions are based on 6 bins for values <2, 2-1, 1-0, 0-1, 1-2, >2)
- binz for onehot-encoded, bzor for ordinal, bzbn for binary
- each accepts parameter bincount for integer number of bins
- bincount defaults to 5
- where if bincount is odd the center bin straddles the mean
- and if bincount is even the center two bins are on different sides of the mean
- also updated inversion transform for standard deviation bins to return bucket midpoint instead of left point

- consolidated time-series transforms into two master function sets
- consolidated numeric partition string parsing transforms into two master function sets
- altogether saved about 4400 lines of code

- a few transfomation category consolidations to make use of common transformation functions
- by making use of the new processdict defaultparams option
- consolidated transformation categories splt/spl8/sp15/sp16 to use common transformation functions
- consolidated transformation categories sp19/sp20 to use common transformation functions
- consolidated transformation categories spl2/spl5/spl7/spl9/sp10 to use common transformation functions
- consolidated transformation categories sbst/sbs2 to use common transformation functions
- consolidated transformation categories sbs3/sbs4 to use common transformation functions
- altogether saved about 5000 lines of code
