BandQ: spruce lines with neutrals

• Releasing BandQ sprucing and HLT2 lines related to neutrals and downstream tracks.
• Moving all imports to the beginning of the file.
• Changing line construction function from HltLine to Hlt2Line
• Removing an unused variable

All changes made to HLT2 are moved to another MR(!2771 (merged)) to make this MR only relevant to Sprucing.

changed title from Draft: BandQ sprucing and HLT2 lines related to neutrals and downstream tracks to Draft: BandQ sprucing and HLT2 lines related to neutrals and downstream tracks.

@mengzhen @yajing For my curiosity, do you have some rough rate / bandwidth estimation for these lines? Would be good to always list some number in any MR.

Hi @yajing (cc @mengzhen ), thanks for the contribution. I don't see any outstanding problem with spruce_bandq.py but you're also adding some independent Hlt2 changes. To avoid further inconvenience in merging stuff I suggest separating your Hlt2 and Sprucing requests to 2 different MR, what do you think @abertoli @nskidmor ?
