Replace `structopt` crate completely with `clap` crate

[thaodt]

We need to replace structopt crate completely with clap crate. At the moment, rustsec advisories db id RUSTSEC-2024-0370 marked it as unmaintained, see dependency tree below:

    ├ proc-macro-error v1.0.4
      └── structopt-derive v0.4.18
          └── structopt v0.3.26
              ├── bitrade v0.1.0
              └── database v0.1.0
                  └── bitrade v0.1.0 (*)

more details here.

Describe the ideal solution

Using clap instead.
