Refactor plot commands

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

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

💡 Note
this took around 27min 18sec in total on my machine with 14min 45sec for the inbreeding section only and 12min 33sec for the rest
