What does this PR do?

Clean take-over from #391

Uses full SEED information (adds network and location) when comparing e.g. pick.waveform_id and tr.stats in a number of functions. Mostly importantly template_gen, but may also include mag_calc and others.

Why was it initiated? Any relevant Issues?

#388

In situations where the desired template or trace contains unique picks with the same Station and Channel, but different location and/or Network codes (e.g. separate sensors in one borehole), current behavior does not differentiate between them.

Assorted to-dos:

• utils.correlate funcs all return cccs, no_chans, and chans. chans only includes station.channel, which then gets passed to Detection objects. Allow for full seed chans in Detection
• Track down all the possible effects of using a full seed id chans attribute for Detection objects...could touch quite a lot...
• Lag calc UsedChannel only uses station.channel. Allow for full seed option.
• Add depreciation warnings
• Add docs "Help" page for adding full SEED IDs to Pick objects and link from depreciation warning.
