feat: `--async` option for compiled binary (CLI)

[jjangga0214]

Hi!

When using compiled binary (by cargo install dsync, not cargo add dsync), --async option is not there. I hope it's to be supported.

What do you think?

you need to compile it with the feature enabled, async is not a default feature

use cargo install dsync --features async

Yes, but that does not mean it will create async code, in my experience. And the freedom to choose on Runtime is still cool, IMHO.

i dont quite understand what this issue is about, so some general information:

for async code to be generated, you need to:

• enable feature async at compile time
• enable via flag --async at runtime

Oh, I checked --help but missed reading --async. Probably I thought I did cargo install dsync --features async but actually cargo install dsync. Thanks for the clarification!
