Extract SPARQL client

Summary:
The sparql-client crate is based on oxigraph components
and extracted from fantoir-datasource crate.

The goal is to allow SPARQL queries in any Rust project.

As both fantoir-datasource and sparql-client needs
to build an HTTP client with specific configuration
(gzip, deflate, user-agent), common code previously
in fantoir-datasource is migrated to a specific support
crate, ds-http-client.

The ds- prefix has been chosen for small support libraries
for the datasources project.
