Yoctopuce dev e57aa7e70a py/obj: Fix nan handling in object REPR_C and REPR_D. ...

CPython math.nan is positive with regards to copysign.  The signaling bit
(aka sign flag) was incorrectly set.

In addition, REPR_C and REPR_D should only use the _true_ nan to prevent
system crash in case of hand-crafted floats.  For instance, with REPR_C,
any nan-like float following the pattern
`01111111 1xxxxxxx xxxxxxxx xxxxx1xx` would be switched to an immediate
object or a qstr string.  When the qstr index is too large, this would
cause a crash.

This commit fixes the issue, and adds the relevant test cases.
