Executor agnostic async TFTP implementation, written with [smol]
building blocks. Currently it implements only server side.

The following RFCs are implemented:

* [RFC 1350] - The TFTP Protocol (Revision 2).
* [RFC 2347] - TFTP Option Extension.
* [RFC 2348] - TFTP Blocksize Option.
* [RFC 2349] - TFTP Timeout Interval and Transfer Size Options.

Features:

* Async implementation.
* Works with any runtime/executor.
* Serve read (RRQ) and write (WRQ) requests.
* Unlimited transfer file size (block number roll-over).
* You can set non-standard reply [`timeout`]. This is useful for faster
  file transfer in unstable environments.
* You can set [block size limit]. This is useful if you are accessing
  client through a VPN.
* You can implement your own [`Handler`] for more advance cases than
  just serving a directory. Check [`tftpd-targz.rs`] for an example.

# Example

```rust
use async_tftp::server::TftpServerBuilder;
use async_tftp::Result;

fn main() -> Result<()> {
    smol::run(async { // or any other runtime/executor
        let tftpd = TftpServerBuilder::with_dir_ro(".")?.build().await?;
        tftpd.serve().await?;
        Ok(())
    })
}
```

Add in `Cargo.toml`:

```toml
[dependencies]
smol = "0.3" # or any other runtime/executor
async-tftp = "0.3"
```
