[Feature] Option to Keep Prefixes in Filenames, but not in H1

[electblake]

Problem

Using ZK prefixes, or the built-in Unique Note Creator plugin then adds the prefix to the H1 which makes omnisearch and other issues.

Plugins I use that would benefits:

• https://github.com/Dyldog/luhman-obsidian-plugin
• https://help.obsidian.md/Plugins/Unique+note+creator

Proposed Solution

• Add a new setting "keep prefixes in filename"
• Add ability to define multiple regex expressions to match and return a prefix during title sanitization process
• Prefix Regex rule ordering matters as some prefixes may be simpler than others

I've actually already built this using the following setting screen - have been testing locally before submitting this.

Today the plugin was updated so I had to rebuild my forked changes - so seems like time to share this for review 🙏🏼
