This is the initial port to github actions. Still pending are the SSL and client SSL cert tests which are currently being skipped. But perfect is the enemy of the good here, and having no CI because travis-ci keeps not working is unacceptable.
This is fixing a double readyForQuery message being sent from the backend (because we were calling sync after an error, which I already fixed in the main driver). Also closes#2333
* Fix pg-query-stream
There were some subtle behaviors with the stream being implemented incorrectly & not working as expected with async iteration. I've modified the code based on #2050 and comments in #2035 to have better test coverage of async iterables and update the internals significantly to more closely match the readable stream interface.
Note: this is a __breaking__ (semver major) change to this package as the close event behavior is changed slightly, and `highWaterMark` is no longer supported. It shouldn't impact most usage, but breaking regardless.
* Remove a bunch of additional code
* Add test for destroy + error propagation
* Add failing test for destroying unsubmitted stream
* Do not throw an uncatchable error when closing an unused cursor
