cargo install mmtc fails with import scope errors

at the `compiling mmtc v0.2.14` step, the cargo build fails with a bunch of errors like this:

```
error: cannot find derive macro `Parser` in this scope
--> /home/dried/.cargo/registry/src/github.com-1ecc6299db9ec823/mmtc-0.2.14/src/cli.rs:8:10
|
8 | #[derive(Parser)]
| ^^^^^^
|
note: `Parser` is imported here, but it is only a trait, without a derive macro
--> /home/dried/.cargo/registry/src/github.com-1ecc6299db9ec823/mmtc-0.2.14/src/cli.rs:1:5
|
1 | use clap::Parser;
| ^^^^^^^^^^^^

error: cannot find attribute `clap` in this scope
--> /home/dried/.cargo/registry/src/github.com-1ecc6299db9ec823/mmtc-0.2.14/src/cli.rs:9:3
|
9 | #[clap(version)]
| ^^^^
|
= note: `clap` is in scope, but it is a crate, not an attribute
```
