"Orchestral" and "Brass Ensemble" missing Euphonium and baritone-horns

orders.xml missing Euphoniums and baritone-horns for orchestral and brass ensemble.
They are not too uncommon.

PR coming up.

Orchestral:
Sort after trombones, before tubas. Baritone Horns first, because it could also be a "Tenorhorn" (german variant which is always above Bariton/Euphonium). Same as in Concert Band.

Brass Ensemble:
Both Baritone horns and Euphoniums missing, but I would sort them Between horns and Euphoniums as their function is slightly differnt here. But if you like, I can also sort them between trombones and tubas as everywhere else.

Templates also needs update.
