Add minimal supported Rust version

[Polkas]

I can not compile tergo on my local my os .
I will try to investigate it.
It works totally fine on Linuxed based machine (github code spaces).

error: failed to select a version for `env_logger`.
       ... required by package `tergo-lib v0.2.6`
       ... which satisfies dependency `tergo-lib = "^0.2.5"` of package `tergo v0.1.0 (/Users/maciejnasinski/Documents/tergo/antidotum/tergo/src/rust)`
   versions that meet the requirements `^0.11.3` are: 0.11.5
   
   the package `tergo-lib` depends on `env_logger`, with features: `anstream` but `env_logger` does not have these features.
    It has an optional dependency with that name, but that dependency uses the "dep:" syntax in the features table, so it does not have an implicit feature with that name.
   
   
   failed to select a version for `env_logger` which could resolve this conflict

Wnat rust version are you using?

rustc --version
rustup show

Can you print the result of the above?

It was too old:) I reinstall rust and it is fine now. Please feel free to close the item. The only benefit is to consider setting a minimal required rust version.

It was old;p
