Validation for Float type not matching spec

[jsotobroad]

I was writing a wdl with this line in the task definition

Float vaf = .01

and was getting this error when validating

Error: Invalid WDL: ERROR: Unexpected symbol (line 28, col 16) when parsing 'e'. Expected identifier, got 01. Float vaf = .01 ^ $e = :identifier <=> :dot :identifier -> MemberAccess( lhs=$0, rhs=$2 )

if I change it to

Float vaf = 0.01

it's fine but I think looking at the spec the first iteration should work too - https://github.com/openwdl/wdl/blob/master/versions/1.0/SPEC.md#whitespace-strings-identifiers-constants

$float = (([0-9]+)?\.([0-9]+)|[0-9]+\.|[0-9]+)([eE][-+]?[0-9]+)?

Easily worked around just a little annoying. This was run on a FireCloud method so I assume its one of the more recent versions? (cromwell 34) but 🤷‍♂️

I believe the E syntax is also not supported.
