this MR turns `./.nushell/` into a directory module by
- adding `mod.nu`
- exporting all the modules

all uses of `.nushell/` have been fixed to not mention `.nu` internal modules anymore.

> 💡 **Note**  
> the `.nushell venv` module has been removed because, when the `$venv.VENV` activation script is not there, Nushell can't parse the whole `.nushell` module, which is very annoying to have to rely of the state of the external filesystem to be able to simply parse a module...

## new structure for the repository
- benchmarks are in `./benchmarks/` and can be run with either `cargo run --package benchmarks --bin <bench>` or the commands in `./benchmarks/README.md`
```
├── Cargo.toml
├── README.md
└── src
    └── bin
        ├── commit.rs
        ├── fec.rs
        ├── linalg.rs

        │   └── field.rs
        ├── recoding.rs
        ├── setup.rs
        └── setup_size.rs
```

- examples are now in `./bins/` as standalone binaries and can be run either with `cargo run --package <pkg>` or with the help of the `cargo bin` command from `.nushell/cargo.nu`

- Nushell modules are now located in `./.nushell/`

## changelog
apart from the changes to the general structure of the repo:
- `binary.nu` -> `.nushell/binary.nu`
- new `cargo bin` command from `.nushell/cargo.nu`
- `error throw` is now defined in `.nushell/error.nu`
- main TOML has been greatly simplified because the dependencies of "examples" have been moved to the associated crates
- the rest is basically the same but in the new structure

up until now, elliptic curves have been hardcoded in the benchmarks, forcing to run them on all supported curves...

this MR makes it possible to use only a subset of curves.

> 💡 **Note**  
> when running the same commands from !104, minus the "inbreeding" ones which are not affected by this MR, the time goes from 12min 33sec to 4min 28sec 🎉 


## TODO
- [x] setup
- [x] commit
- [x] recoding
- [x] fec
- [ ] linalg
- [ ] setup size
- [ ] field operations
- [ ] group operations

> 💡 **Note**  
> because all the unticked bullet points above are far from critical to the paper and do require to measure all curves, i won't change these for now

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`
