feat(no-sharereplay-before-takeuntil): new rule

[JasonWeinzierl]

New rule to catch putting shareReplay before takeUntil with refCount: false.

• This rule is added to the strict config.
• This is using the same algorithm as no-unsafe-takeuntil to determine if takeUntil itself is in a valid position; this rule will not trigger if takeUntil is invalid.
• This rule also cannot handle complex scenarios like composing multiple observables or refCount set to a variable with unknown boolean value.

Resolves #108
