[New Feature] Cloze by Replacing or Regex

[zinc0x1E]

Supporting replacement cloze or regex cloze

It's something metioned in #42. The idea is from Obsidian Anki Sync, but I really like the syntax to declare an Anki card of this plugin, so I decide to implement a similar thing here.

I'm not sure whether new PR will be reviewed and merged, but I do want this feature, and I'm adding more features I wanted to my fork. If new PR is still accetaple here, I will be more than happy to contribute here instead of maintaining my own fork.

example:

id: 1691599660053
tags:
  - equation
clozeReplacements:
  - /1(.)3/g, $1
  - /456/g
  - r"raw text mode"
  - shorthand
---

A function with period $L$ can be ==written== as a __Fourier Series__:  
123
456
123456 raw text mode 456123 foo bar
a shorthand for raw text mode

===
Extra field

above code block in obsidian would compile to this anki text

A function with period  Mathjax  can be {{c1::written}} as a Fourier Series:
{{c2::2}}
{{c3::456}}
{{c2::2}}{{c3::456}} {{c4::raw text mode}} {{c3::456}}{{c2::2}} foo bar
a {{c5::shorthand}} for {{c4::raw text mode}}
