removed driver dependencies

[derkan]

Hi Samuel, I hope you are doing well. I removed db driver dependencies in this PR.

PR provides using pgx/stdlib driver instead of pg(or modernc.org/sqlite instead of mattn/go-sqlite3...). Also this makes exe size smaller when user uses alternate drivers.

Only drawback: user should import his/her driver before using it(not auto imported when imported relevant adapter. And I think mostly users do this beforehand.

Hi Derkan,

It's a breaking change. I can't do this without publishing a "v2".

I've another problem : no time to maintain this seriously. I will test on newer Go versions and update the test matrix and README, but nothing more, at least in short time. It took me almost 3 weeks to reply, it's not very serious as a maintainer, I'm sorry.

The project is stable, it's usable as-is. Next major evolution could involve generics. Also I think code generation is also better then reflection. If something will evolve, it will rather be a revolution.

If you fork durably the project I could mention it in the README. I will not be very available next weeks, but I'll do it, at worse in September.

Samuel.
