One commit of this PR is the same as the one in PR #118.
I think that the current code is too complicated and that it's uncommon that fread() read less than what found with fseek()+ftell(), but then the code reads any short file, as it should, since chances are that some signals would be decoded anyway thanks to error correction, eg. with half of 211212_2142.zip rtlsdr_wsprd can decode the same signal as with the full file:
$ dd if=211212_2142.c2 of=half_211212_2142.c2 ibs=1 count=180026
$ ./rtlsdr_wsprd [...]
Reading IQ file: c2/half_211212_2142.c2
Number of samples: 22500
SNR DT Freq Dr Call Loc Pwr
Spot : -15.08 -0.08 7.040093 0 M0ICR IO91 27
A message about less samples than expected would be useful.
Avoiding the use of fseek() would allow to read the files from a pipe or /dev/stdin (if the check for file extensions allowed that), like was asked in issue #20.
