[Feature]: Option for filtering by location

[Ben-Bitdiddle-DE]

Requirements

• I have updated Mushroom to the latest available version
• I did a search to see if there is a similar issue or if a pull request is open.

Is your feature request related to a problem?

I have a already existing calendar which gets populated automatically out of my hands, it contains entries which are not relevant for me, i could filter them out by having an additional location filter option (like atomic-calander has/does).

Describe the solution you'd like

Like entry title matching also have the option to set a location text matching string.

Describe alternatives you've considered
