[HULUROKU-7877] Replace brs package with @rokucommunity/brs version 0.45.2

[gregomite]

Jira: HULUROKU-7877

• Replace the "brs" package with "@rokucommunity/brs" in package.json
• Use @rokucommunity/brs version 0.45.2 (later versions introduce issues with roca's unit tests)
• Update roca typescript files to use the new namespace "@rokucommunity/brs"

Should we increase the version of roca as well here to 0.26.0?

"name": "@hulu/roca",
  "version": "0.25.0

I think the version bump should be its own commit when we're ready to tag the ROCA project.

@Nowele, maybe we need to merge this PR and the later update should be done in the separate Pr?
