List kysely and drizzle-orm as devDependencies (needed for the tests) and peerDependencies
Use peerDependenciesMeta to mark kysely and drizzle-orm as optional since one is only needed if using the Kysely dialect or Drizzle driver integrations of SQLocal
Also, maybe you should add something to the "Install" section of the README, to clarify that if you want to use the integrations with Kysely or Drizzle, you need to install those dependencies as well.
