25099e6f89 Permit SendBatch with Simple Protocol 
This commit adds support for sending batches of queries via the Simple
protocol with SendBatch. The result appears identically to how it would
if it were created with the extended protocol.

ac6c49c39d Require access to ConnString via Config 
A Config object may be created via ParseConfig and then further
modified. Requiring access to the original ConnString via the Config
helps indicate that the Config is the source of truth as to how the
connection was actually established.

a66b09fbd8 Improve simple protocol / text format 
Increased data type support for simple protocol. Improved test
coverage of simple protocol. This has the additional advantage of
exercising the text encoders and decoders.

c44cda4bb4 Clean up old Go 1.10 build tags 
pgx requires Go modules which requires at least Go 1.11 so there is no
use in build tags to support older Go versions.

c03ac1519e Improve stdlib performance with large result sets 
In a hot path type assertions are expensive. Cache the already correctly
typed interfaces. ~20% improvement with 1000 rows.
