Add lexical analysis example

[vit0rr]

Hey,
I read the README and tried to add a Project topic using the TOML file, but it added my project as a package. So, I added my project directly to the awesome.gleam file and ran gleam run.

If it is wrong in some way, please let me know

Thank you! I think there's a few things that would need to be improved before this could be an example, to prevent new folks from picking up the wrong conventions.

• The README has no documentation
• The public functions have no documentation
• There's an unused module in the src directory
• The modules are not within the package's namespace, instead they are in the top level global namespace
• The token type is using wrong case. "TRUE" means "t_r_u_e" in Gleam

The use of string.slice will make it quite slow also. The string will have to be walked from the start each time, making the cost exponential with the size of the input.

Oh, thank you so much for the review! I'll update the code

Hey @lpil

I've just updated the code. Could you please check if it is ok now? And by The use of string.slice will make it quite slow also you mean all slices I've used on my code?
