Add parsing of decimal constants (e.g., 1.02e+01)
Rather than integers '[0-9]+', numeral constant can now be parsed
according to the regexp '[0-9]+ ([.][0-9]+)? ([eE][+-]?[0-9]+)?'.
This can be used in one of the two following ways:
- using the function `Notation.register_rawnumeral_interpreter` in an OCaml plugin
- using `Numeral Notation` with the type `decimal` added to `Decimal.v`
See examples of each use case in the next two commits.
