Indexed calling of the opted function

[isoux]

In file BareMetal/tree/master/src/syscalls/system.asm If, for example, the system function b_system_delay is called, the CL register is checked 21 times for its turn to be executed...

I suggest code with a table of functions that are indexed. The file size is reduced and the executable is about 50 bytes larger after compilation, but the result is that any selected function is started fast just it opted as all the others. There are still plenty of spots in the table to add new system functions without increasing the table, which currently takes up about 280 bytes.
Take a look at the code that I would suggest as a pull request if you like it, and of course it works for me and has been tested.

p.s.
Another small correction to my code followed.
And another very significant. The code is much faster and right...

Awesome! I’ll look into implementing this as well.

Does that mean I'm welcome to do a pull request or is this idea enough for you to implement in your own way? Anyway I'm glad if it helps!

If you want a PR I would like you to help me how to create it to fit your standards. Maybe this is not modest but I would like to be a "real" contributor. :)

Yes, please create a PR.
