fix: add ./types

fix: make sure that parts of DSN are properly decoded (gajus#314)

DB-connection parameters might have url-incompatible characters in them.
The standard way of dealing with this is urlencoding.

Slonik's old DSN parser supported it, but new one doesn't.

This patch adds urldecoding and urlencoding for username, password and
databaseName

fix: allow to override ssl using ssl option (fixes gajus#313)

fix: add Buffer support to primitive value expressions (gajus#311)

fixes gajus#253

feat: add createDsn and stringifyDsn utilities

feat: change query retry handling (gajus#308)

Move transaction retry handling to the transaction and nestedTransaction
methods and change it so that the handler function is called again
instead of just replaying the queries that are part of the transaction.
Fixes gajus#163.

Add a second parameter to the transaction method to allow users to
define a retry limit per transaction. If a retry limit is given for a
transaction then the global defined retry limit for transactions is
ignored.

Change executeQuery so that it retries individual queries that failed
with a transaction rollback error. Only queries that are not part of a
transaction are retried. The number of times a query is retried is
specified by the global queryRetryLimit configuration. Fixes gajus#176.

The above change also fixes gajus#196 since the transactionQueries array no
longer exists.

BREAKING CHANGE: changes query / transaction retry strategy

feat: add literalValue (fixes gajus#309, gajus#150)

fix: update createTimestampWithTimeZoneTypeParser.ts (gajus#304)

fix: Replace non-null type assertion (gajus#298)

Replace with typescript utility type 'Exclude'
