Add p5-Text-Roman 3.5

This package supports both conventional Roman algarisms (which range
from 1 to 3999) and Milhar Romans, a variation which uses a bar across
the algarism to indicate multiplication by 1_000. For the purposes of
this module, acceptable syntax consists of an underscore suffixed to
the algarism e.g. IV_V = 4_005. The term Milhar apparently derives
from the Portuguese word for "thousands" and the range of this
notation extends the range of Roman numbers to 3999 * 1000 + 3999 =
4_002_999.
