[PATCH 0/4] require Ruby 2.3+, support Ruby 3.1

[Eric Wong]

I figure most workstation and laptop users will have Ruby 2.3+
by now, since the Ruby core team doesn't even support 2.5.

In any case, old versions of dtas remain available for users of
old Rubies; but AFAIK dtas hardly has users atm and isn't likely
to gain more.

Psych 4.x (YAML) distributed with Ruby 3.1 breaks some subtle cases
for us so 4/4 fixes them.

Eric Wong (4):
  require Ruby 2.3+
  get rid of DTAS.dedupe_str wrapper
  move dtas-graph into script/, support Perl for dtas.sh
  use YAML.unsafe_load in Psych 4.x (Ruby 3.1+)
