database/sql driver for libspatialite

Go driver for libspatialite
First you must install both sqlite3 and libspatialite C libraries.
Then
go get -u github.com/briansorahan/spatialitedb, err := sql.Open("spatialite", "my.db")Check out the tests to see more example code.
I think the err InitSpatiaMetaData() error:"table spatial_ref_sys already exists" should be ignored here, users will get the error when opening the same database every time
stmt, err := conn.Prepare(`SELECT InitSpatialMetaData(1)`)
if err != nil {
return nil, err
}
The dependence to mattn/go-sqlite3 require the v2 but this version is incompatible and should be reversed to v1.14.16.
Cf mod.go :
require github.com/mattn/go-sqlite3 v2.0.3+incompatible
Test seem to be failing
