Improvement: describe output could be self-explanatory

[alcuadrado]

Hi, I want to propose a little improvement.

I never remember what surya describe's # and ($) mean, so I have to open this repo every time I use surya.

Adding a small explanation in the output would be helpful. Alternatively, the symbols can be replaced with words.

Hey @alcuadrado! 👋 You're totally right! 😄

Would emoji characters make it any better? Like 💵 & 🛑 ? Or do you think words would be a better experience?

I think the payable one can be pretty evident with $ or 💵, but the non-constant one is more confusing. Specially the relationship between them, as $ implies #.

I like that the output is concise, and using words for everything may be too much text. What about adding something like this at the end?

$ = payable, non-constant function
# = non-constant function

Using emojis is cool, but not widely supported, so take into account that adding them requires some kind of platform detection.
