python-twisted: upgrade to version 13.2.0

Changes:
* upgraded python-twisted to latest upstream
* dropped PR because of PV increase
* updated LICENSE checksum because new contributors have been added to the file
* dropped bin package because resulting package was empty:
  - file _c_urlarg has been removed with this commit:
    https://twistedmatrix.com/trac/changeset/31167/trunk/twisted/protocols
  - file cBanana was not packaged even in previous version, upstream removed it ages ago.
