littletable 2.2.5

• Enhanced Table.by, Table.all, and Table.search methods to accept a field name that is not a valid identifier by using a callable interface:

    tbl = lt.csv_import(
        "https://github.com/lukes/ISO-3166-Countries-with-Regional-Codes/blob/master/all/all.csv?raw=true"
        )
  
    # field "region" is a valid Python identifier
    regions = list(tbl.all.region.unique)
  
    # field "sub-region" is not a valid Python identifier, use callable interface
    sub_regions = list(tbl.all("sub-region").unique)
  

• Added examples/pyscript/matplotlib.html example, showing how to use littletable within a Pyscript static HTML file.

• Fixed minor code error in Table.by when determining if an index is unique or not. (Not a bug, just fixed some bug-prone code.)

• Expanded peps.py example to Jupyter Notebook PEPs data demo.ipynb.

• Renamed delete_index to drop_index for more symmetry with SQL. delete_index is retained for compatibility.
