Made lib no-std

[uandere]

This pull request adds no_std functionality to the library. This allows for embedded development using textplots, although testing is needed to confirm this possibility.

This is done by introducing new drawille-nostd crate, which does not rely on standard library features. Now, when adding textplots to Cargo.toml dependencies with default-features = false, it will use drawille-nostd crate with reduced functionality (no color support):

# using no_std functionality
textplots = {version = "*", default-features = false}

By default, std feature is enabled, so you can also use all library's functionality like before, without any changes.

@Kezii @TDHolmes what do you guys think about this?

This was discussed on #14 , how are you handling drawile-rs & colored? Those are std reliant dependencies aren't they?

Hi, @TDHolmes! I separated std and no_std functionality by providing new drawille-nostd crate. Now when adding textplots to Cargo.toml with default features (std feature enabled, no changes required), we're using drawille and colored. Otherwise, when default-features = false is specified, we're swithing to the functionality of the drawille-nostd crate.

What do you think about that?

Sweet! Sounds good

Thanks! Planning to test this out next week on stm32f4 =)
