Introduction, and a few pending contributions

[Clement Igonet]

Hello,

A short introduction: I'm Clément, a software engineer of 24 years, the last four in the space ground segment (satellite operator, mission-control observability). I started contributing to Yamcs this month and would like to keep at it.

Currently open, in case any of it is useful to look at:

* Small fixes with tests: https://github.com/yamcs/yamcs/pull/1156 (XTCE DTD hardening), https://github.com/yamcs/yamcs/pull/1161 (algorithm names with spaces, issue 1137), https://github.com/yamcs/yamcs/pull/1162 (PUS events without a source, issue 1058)
* Two adoptions of stalled community PRs, with their authors credited: https://github.com/yamcs/yamcs/pull/1157 (cFS event decoder robustness) and https://github.com/yamcs/yamcs/pull/1158 (aggregate outputs for script algorithms)
* The quickstart compose now starting the simulator: https://github.com/yamcs/quickstart/pull/51
* A containerised dev build/run proposal: https://github.com/yamcs/yamcs/issues/1160
I sent my signed CLA to ya...@spaceapplications.com yesterday.

Separately, I posted a roadmap proposal for the grafana-yamcs datasource (alerting, live streaming, signed catalog release) and would value maintainer opinions on the direction before anything is built: https://github.com/yamcs/yamcs/discussions/1159

No urgency on any of this; mostly saying hello, and happy to adjust anything during review.

Clément
