Create table odb_logs

Hi Team!

Thanks for this very useful plugin!

At every init of the plugin it tries to create table (prefix)odb_logs. If the table already exists this throws notifications that are not helpful. E.g. in conjuction with https://www.ads-software.com/support/plugin/wp-security-audit-log/ this causes the log to be flooded with these notifications. Or ref a similar issue reported with https://www.ads-software.com/support/topic/create-table-if-not-exists-wp_odb_logs-on-every-request-neccessary/

It would be great if you could further optimize this plugin by preventing those notifications with some useful functions like maybe_create_table() or dbDelta().

Cheers!
