This patch adds FromFS function and lets you use the new go:embed directive to add the migration files to the binary.
Also, migration tests use an in memory FS impl instead of working with tmp directories.

Add Session wrapper
With this patch we can now use gocqlx like:
```
session.Query(`SELECT * FROM struct_table`, nil).Get(&v)
```
instead of (old format):
```
gocqlx.Query(session.Query(`SELECT * FROM struct_table`), nil).Get(&v)
```

Depending on what is set, schema agreement is checked before each file or before each statement.
Awaiting schema agreement after every migration has run is always done.
