v0.2.1

• Allow disable mutation observer #43
• Fix reverse engine bucket selection #40
  1. The selection of bucket for each filter in ReverseIndex would
     needlessly fallback to the default bucket in some cases (even if a
     better bucket could be available).
  2. Some plain patterns would not be indexed properly if we expect
     their last token to be a potential partial match. For example
     ||foo.com/bar would not always match foo.com/barbaz, if bar (the
     last token of the filter) was selected as "best token". The
     work-around is to ignore the last token of plain patterns (to be
     safe).
• Allow filters without specific resource type to match any cpt #42
