fastaq_chunker - Splits sequences into equal sized chunks

usage: fastaq_chunker [options] <infile> <out> <chunk size> <tolerance>

Splits a multi sequence file into separate files. Splits sequences into chunks of a fixed size. Aims for chunk_size chunks in each file, but allows a little extra, so chunk can be up to (chunk_size + tolerance), to prevent tiny chunks made from the ends of sequences

Name of input file to be split
Prefix of output file. If --onefile used, then name of single output file
Size of each chunk
Tolerance allowed in chunk size
