Metadata filter output is passed through an Awk script comparing floats

architectural differences (e.g. x86-32 vs. x86-64).

tested on Linux x86-32/64 and Mips (Qemu)
v3:
- avoid precision loss due to rounding of float values
v2:
- removed CPUFLAGS work-around for ssim filter issue
- added metadata float value post-processing script

This seems not to work (normal x86-64 linux) but maybe ive done something silly

It seems that my assumption that iterating a for-in loop with numerical
indexes would walk the array in linear order does not apply to all
versions of Awk. I'm testing with GNU Awk 4.1.3, what version of Awk is
installed on your computer?
Will rework the loop and post a patch update.
Regards,
Tobias
