create SQLite pragma kdf_iter as SpecificOption

Hi Devart,

we use SQLCipher to crypt SQLite - Databases. With SQLCipher V3.x the kdf_iter is default 64000 which causes Speed - Problems on some slow machines.
It would be great if you can implement this

pragma kdf_iter= <value>

this pragma should be called right after pragma key =

as Specific-Option for SQLite.

Hello,

This is not a standard sqlite pragma. In our product, we support only those pragmas, which are supported in the official version of the library. If you have a Source Edition, we can show you where to add necessary changes.
