Refactor plot commands (dragoon/komodo!104)

this MR moves run and plot commands from `examples/benches/README.md` to
- `scripts/setup/`: `run.nu` and `plot.nu`
- `scripts/commit/`: `run.nu` and `plot.nu`
- `scripts/recoding/`: `run.nu` and `plot.nu`
- `scripts/fec/`: `run.nu` and `plot.nu`
- `scripts/inbreeding/`: `build.nu`, `run.nu` and `plot.nu`

to generate all the figures at once
```bash
use scripts/setup/run.nu; seq 0 13 | each { 2 ** $in } | run --output data/setup.ndjson
use ./scripts/setup/plot.nu; plot data/setup.ndjson --save ~/setup.pdf

use scripts/commit/run.nu; seq 0 13 | each { 2 ** $in } | run --output data/commit.ndjson
use ./scripts/commit/plot.nu; plot data/commit.ndjson --save ~/commit.pdf

use scripts/recoding/run.nu; seq 0 18 | each { 512 * 2 ** $in } | run --ks [2, 4, 8, 16] --output data/recoding.ndjson
use ./scripts/recoding/plot.nu; plot data/recoding.ndjson --save ~/recoding.pdf

use scripts/fec/run.nu; seq 0 18 | each { 512 * 2 ** $in } | run --ks [2, 4, 8, 16] --output data/fec.ndjson
use ./scripts/fec/plot.nu; plot encoding data/fec.ndjson --save ~/encoding.pdf
use ./scripts/fec/plot.nu; plot decoding data/fec.ndjson --save ~/decoding.pdf
use ./scripts/fec/plot.nu; plot e2e data/fec.ndjson --save ~/e2e.pdf

use ./scripts/fec/plot.nu; plot combined data/fec.ndjson --recoding data/recoding.ndjson --save ~/comparison.pdf
use ./scripts/fec/plot.nu; plot ratio data/fec.ndjson --recoding data/recoding.ndjson --save ~/ratio.pdf

./scripts/inbreeding/build.nu
./scripts/inbreeding/run.nu --output data/inbreeding.nuon
./scripts/inbreeding/plot.nu data/inbreeding.nuon --save ~/inbreeding.pdf
```
