More progress towards #2067!

This PR takes a stab at tweaking `docs/frontends/queues.md` to
incorporate additions from PRs #2164 and #2174.

This PR makes progress towards #1810. It implements the python oracle
for PIFOs generalized to n flows, now known as Round Robin queues. Just
as with the PIFO, if a flow falls silent, the remaining flows will take
their turns. That flow effectively skips its turn. To re-generate the
test files with 20000 commands and a max length of 16, type in the
command line after navigating to the directory calyx/calyx-py/calyx

```
./gen_queue_data_expect.sh
```

Additionally, this PR also implements the Calyx version of Round Robin
queues in rr_queue.py. This was originally supposed to be its own PR,
but I thought it might be more complicated if I branched off a branch.
To run these tests, type in the command line
```
runt -i "rr_queue"
```

It looks like `calyx-py/test/correctness/queues/*.py` was removed from
the path of its runt test by #2177: i.e. the old `fifo`, `pifo`, and
`pifo_tree` tests aren't running at CI. Was this intentional? In case it
wasn't, I've made a minor fix to `runt.toml`.

This PR ties off the last half of #1810. It implements the python oracle
and Calyx eDSL for strict PIFOs, which are generalized to n flows. Flows
have a strict order of priority, which determines popping and peeking
order. If the highest priority flow is silent when it is its turn, that
flow simply skips its turn and the next flow is offered service. If that
higher priority flow get pushed to in the interim, the next call to
pop/peek will return from that flow. To re-generate the test files with
20000 commands and a max length of 16, type in the command line after
navigating to the directory calyx/calyx-py/calyx
```
./gen_queue_data_expect.sh
```
To run the runt tests on the eDSL implementation, type 
```
runt -i "strict"
```

This PR begins progress towards addressing #1958. It updates the
algorithm used by `fud2` for finding paths from input files to output
files to take in operations which have many inputs and outputs.

The behavior concurs with the current `fud2` in some but not all cases
and does not maintain `fud2`'s always finding the shortest path of
operations.

Specifying operations themselves and emitting the Ninja file still
assume single state inputs and outputs. This will be changed in further
PRs.

There was a small change to the user facing types in Rhai which caused
fud2 to fail compilation for rhai v1.19. This branch fixes that.

Implements the option to create several (default 2) FSM registers that
represent dynamic control flow, so that queries can be split between all
of identical registers.
