share/FASTQFile.py: version 0.3.0

- attempt to improve performance of SequenceIdentifier class by using string parsing
  rather than regular expressions
- add new method 'is_pair_of' to SequenceIdentifier (checks if another SequenceIdentifier
  object forms R1/2 pair with this one)
- changed way FastqRead does lazy load of seqid attribute, and introduced new 'raw_seqid'
  attribute (gets back the input sequence header line supplied when the FastqRead object
  was instantiated)
- New function 'fastqs_are_pair' (checks that corresponding read headers match between
  two FASTQ files).
