Subject: [PATCH 2/3] dec2flt: Simplify imports and module surface

The import has been unnecessarily complicated since ParseFloatError::Invalid is not longer used unqualified.
The pfe_* functions do not need to be public any more since the only other use site, from_str_radix for floats, has been removed.

The argument was a remnant of an earlier, needlessly complicated implementation.
