Flag Casing

[Benjamin Frost]

Use Case:
To avoid confusion and casual mistakes, getters on $ld.flags should be indifferent to casing.

Acceptance Criteria:

• Interactions with flags should be indifferent between kebab casing and camel casing
  • e.g., $ld.flags['feature-flag'] and $ld.flags.featureFlag
• The solution should be usable by older browsers

This should also work for LDRouteGuard and the redirects. Ideally, this would also be opt-in to avoid surprises.
