feat(sql):Added File based migrations

[Sir-Thom]

Added a way to do file based migrations
I have also added in the README.md. how to do it.

this solve issue #1347

What is the actual intention? Should it be a built time thing or are the migrations supposed to be dynamically loaded from the user's system (requiring you to bundle the migration files with your app, for example with the resources feature).

To me the build time approach makes sense (and the issue sounds like that to me) but your implementation loads it from the system running the app.

p.s. also, is there a way to get rid of Box::leak? Not a fan of that in this context tbh.

Yeah, it makes more sense to do it via build time. I am currently reworking on it to create an autogenerated file created during build time that can be used as a migration list so the user only has to set 2 env one for the project root and one for the migration directory and the user only has to do . add_migrations ("sqlite: test. db", migrations())
here what it look like currently
