Tiny package for determination of tabular file formats based on file extensions.
It is intended to be the base both for TableIO.jl and for the Pluto.jl tabular data import functionality.
get_file_type("test.csv") # gives TableIOInterface.CSVFormat()
get_file_type("test.zip") # gives TableIOInterface.ZippedFormat()
is_extension_supported("csv") # gives true
is_extension_supported("foo") # gives false
etc.
