Status the implemented rule set to detect CEST images and theire revision in formation is to "narrow".

The rule should be changed to this set:

1. Sequence name (tSequenceFileName) must either
   1. start with the substring CEST (case insensitiv!), or
   2. contain the substring _CEST (case insensitiv).
2. Sequence name (tSequenceFileName) must contain the substring _Rev (case insensitiv).
3. All numbers after _Rev represent the revision number; until either
   1. the next _, or
   2. end of sequence name
