Update VISSR version (latest VISS v3)

[slawr]

CDSP currently uses an VISSR commit that points at in-development support for VISS v3. The upstream project has now completed development of VISS v3 support and we should upgrade

Work plan:

• Determine upstream commit to use
• Check upstream Dockerfile builds (upstream does not maintain their Dockerfile alongside code updates)
• Sanity test that IoTDB connector still works for get/set
• Check if any CDSP documentation needs updating

Upstream commit

Upstream recently made release v1.0. However on inspection the tag is 200 commits behind master. Asked maintainers whether that is expected.

Placing on hold whilst waiting for feedback from upstream maintainers

Upstream #commit

Ulf reported that tag was pointing at wrong commit and corrected it.
Resumed development on that current head commit 9f59c4f720.

VISSR build

Experienced build issue using the upstream Dockerfile.rlserver. Raised issue in upstream VISSR COVESA/vissr#115
Waiting for feedback from VISSR devs.
