adding modifications for re-reco

General cleanup:

• config files
• snakemake configs
• updating the step_*cfg.py files

Improvements to NANO:

• throughput : fill tables with single loop plus two possibilities
  • use reserve and push_back instead of resize
  • declare columns as class variables and resize for first event + use edm::Span
• energy and time as float (i really doubt we need a double)
• change compression algorithm

Some numerology on the NANO using pedestal run 1726225194 (measured in vocms1002 using maxThreads=4 and 50k events)

With the default LZMA compression 9 (as in the TB) I get the following. The major improvement I'm convinced is because instead of doing two loops (one over DIGIs and one over RecHits) one moves to a single loop.

Version	Throughput [ev/s]
Updated from !46 (merged)	113
Move to reserve+push_back + 1 loop	230
Move to 1/run+edm::Span + 1 loop	230

However moving from LZMA compression to ZSTD the gain in throughput is remarkable. There's an increase in the file size (50%) but I would say it's still ok for our purposes.

Compression	Level	Throughput [ev/s]	Size [MB] (50k events)
LZMA	9	230	118
LZMA	5	248	118
ZSTD	9	351	155
ZSTD	5	1764	175

So in this merge request I propose to use for NANO:

• edm::Span for the filling (tbc if it pays off with ZS events)
• ZSTD + compression 5

Maybe @hqu has additional suggestions.
