Description

Right now, the _txlock connection parameter determines which BEGIN statement is used to start a transaction. I'd like to be able to pick this at a per-transaction level. I don't think there's a way of exposing this functionality to database/sql, but it would be good to add an option there eventually. I'm imagining adding:

func (c *SQLiteConn) BeginWithType(t TransactionType) (driver.Tx, error)

type TransactionType int

const (
  Deferred TransactionType = iota
  Immediate
  Exclusive
)

Research direction
Examine the current `Begin` method in `SQLiteConn` to understand how transactions are started. Implement a new `BeginWithType` method that accepts a `TransactionType` enum (Deferred, Immediate, Exclusive) and uses the corresponding `BEGIN` statement. Add tests for each transaction type and update the documentation. Consider whether this can be integrated with `database/sql` or remains driver specific.
