Add "require" option and beta image publish workflow

[varthe]

Issue: #14

Currently, when comparing two values, we use the .includes() function. For example:

• [1,2,3,4,5].includes(3) will return true because the number 3 appears in the array
• "The quick brown fox jumps over the lazy dog".includes("fox") will return true because the word fox is present in the string

This is safer than using x === y and works 99% of the time.

The user who reported the issue says they have a condition for the keyword anime. They want anything with that keyword to trigger a specific filter. They came across a movie containing the keyword based on anime which incorrectly triggered their condition, because we use the .include() function. So what happened was:

• "based on anime".includes("anime") -> true

To help with this I added a new require option which will only return true if the values match exactly.
Also, this change will first be released in the new beta image to allow the user to test it before we make a public release. This is because we don't want to accidentally brick people's existing implementations.

Ignore the spacing changes they're just automatic formatting from an extension.
