Sequel support

[jonatas]

Discussing database performance with Ruby folks on Reddit, I got this excellent comment:

Went there to say the same. It also have a huge pack of plugins, many of them is performance oriented. Like tactical_eager_loading, rcte_tree > It took me some effort to switch my team to Sequel, but after all not a single developer wants to work with AR again. So give it a try, it’s awesome

We should think about supporting Sequel and build a small path, which can be:

require "timescaledb" # detects your ORM framework or Plain PG
require "timescaledb/sequel" # only loads Sequel overloading
require "timescaledb/active_record" # only AR
