When input file/output file are specified, tries to read input and open output, if these test fails it prints a proper message and ends.
When HiFi-UI is used it doesn't enforce input and output file checks until start of decoding.
Updates minimum numba, numpy and scipy versions.
Found weird issues if any of these versions is lower than the ones specified.
Adds better file I/O checks.
