* Unknown arguments are now silently ignored. If this results in
  the tool not being able to run, the usage information of the tool
  is printed instead of the general fdstools usage.
* Seqconvert no longer crashes on an empty line in the input.
* Libconvert now maintains the order of prefix/suffix sequences.
* Allele names with aliases other than 'X' or 'Y' are now correctly
  recognised. These were previously rejected as 'unknown format'.
* Fixed bug where a prefix/suffix other than the first listed in
  the library file was sometimes used as the canonical sequence.
* Sequence format conversion from raw to TSSV-style sequences now
  attempts to match the prefix, suffix, and STR pattern to
  non-matching sequences on a best effort basis. This is
  especially useful when converting to allelenames (which is done
  via TSSV-style sequences), since it results in an allele name
  that matches more closely the names of other alleles.
* Generating allele names for sequences that lack a prefix and/or
  suffix is now supported (by adding a variant description that
  deletes the entire prefix/suffix).
