Lines with charged hyperons as long tracks

Depends on Rec!2875 (merged)

The most abundant, potentially cleanest channels for reconstructing hyperons as long tracks are added.

• \Omega^-\to\Xi^-\pi^-\pi^+ as self tagging decay (very displaced 3-prong decay, no PID cuts needed)
• \Lambda_c^+\to\Sigma^-\pi^+\pi^+ (from b)
• \Xi_c^+\to\Sigma^+ K^-\pi^+ (from b)
• \Xi_c^+\to\Xi^-\pi^+\pi^+ (from b)
• \Xi_c^+\to\Omega^- K^+\pi^+ (from b)

All from b decays will be dominated by background without dedicated RICH info. Naively, hyperons should have large PIDp if they are above threshold (momentum cuts are chosen accordingly) - so rather tight PIDp cuts are made to reduce the rate.

In the future these lines should become selective persistence, storing the RICH raw banks to develop dedicated hyperon PID if considered feasible.

No significant impact on throughput was seen from adding new proto-particle species.
