Major Changes

Create new RomanNumeralTitleCard card type based off the Devilman Crybaby style I posted here
- card_type identifier is roman or roman numeral
- Utilizes the episode text to create the roman numeral, so episode_text_format should be either {episode_number} (the default) or {abs_number}
  - Technically doesn't go beyond ~3,000, but that seems like a non-issue..
- Example of the card:
- Similar to LogoTitleCard, aspects of the card can be customized using extras, like so:
```
font:
  color: "#000000"
extras:
  background: white
  roman_numeral_color: "#4489C2"
```
- Also supports blurring, for example:
Made separator between season/episode text modifiable in AnimeTitleCard, StandardTitleCard, and LogoTitleCard
- Use separator extra like so:
```
extras:
  separator: "-"
```
Starting rewriting some of the Wiki pages to have collapsible menus (for easier navigation) - finished Getting Started Page

Major Fixes

Updated multi-part episode title detection
- Made separator character optional in detecting titles like Title - Part 1
- Match written numbers for titles like Title Part One
Use episode number if absolute number is present in an episode text format string but episode has no absolute number
Add seconds option to frequency scheduling (i.e. --frequency 30s)
- Not useful or intended for main TCM scheduling, eventually useful for #194

Fix super edge case title modification for titles starting with numbers and entirely numerical episode text formats
Fix for templates with nested values being improperly copied
