[ANN] libvisio 0.1.7 has been released

[David Tardon]

libvisio is a library for import of MS Visio documents.

List of changes:

- Fix a few memory leaks found by oss-fuzz.
- Fix date and time conversion to string. (tdf#98291)
- Fix number conversion to string. (tdf#76829)
- Fix unit conversion. (tdf#126292)
- Handle more arrow styles. (tdf#126402)
- Fix some issues found by Coverity.
- Disable expanding entities by XML parser as a vulnerability 
  prevention measure. Applications writing VSDX/VDX documents do not use
  entities, so there is no difference in behavior.

If there is anyone who still needs gzip- or bzip2-compressed tarballs,
please let me know and I will upload them too.
