Individual series per token

Changes:
- We only need a single channel per ChanGroup
- Keep ChanGroups around for sample emission
- Encode info about a parsed line in a Point
- Increase in the depth max depth of the point channels 'cause we have
  fewer of them.
- Encode SeriesType as a type of int so we can have some helper
  functions.
- Use a map to cache the series in the poster pending delivery
Make the postPoint a method of ChanGroup
Rename ChanGroup -> Destination
