Implement stream split for spruce lines

This MR aims to include the stream argument for all the new/renamed Spruce lines included in qee_upgrade branch.

Spruce lines not included in the list below do not have a stream argument and default to the proposal found here.
The full JSON file storing all the attributes of the Spruce lines can be found here line_attribute_dict.json

This is the list of lines, the respective stream arguments and the BW from most recent test (it does not include the updated HLT1 sample):
