[DEP] BaseTransformer list for deprecation to BaseSeriesTransformer

[TonyBagnall]

Describe the issue linked to the documentation

we are scrapping the whole BaseTransformer with its grossly inefficient VectorizedDF. This is a list of all files and classes to track changes. Some of these we may be able to just remove, some of it seems unnecessary, my thoughts in brackets.
