ns-eel2 parses numbers without decimal point with atoi(), which causes overflows as it has a lower value range than double. We now mimic this behavior.
Also convert integers in bitwise and modulo operators to the same bit-width as PRJM_EVAL_F to prevent overflows.
Instead, directly include it where it's actually being used.

One fix in the scanner to parse integers (literal numbers without a decimal point) with
atoi, which is what ns-eel2 does. The other fix uses fixed-size int types for type conversions within a few expression operators like bitwise and/or and modulo. Now, the floating-point numbers are converted into the same-size int, depending on the whetherfloatordoubleis used during compilation. Most builds will use 64-bit numbers for both. This prevents further overflows and also more closely resembles what ns-eel2 does internally.The third commit only moves an
#includefrom a header where it wasn't needed to the files which actually use the header's single function declaration.Additionally fixed a warning with Clang as
-Ofastis deprecated.
