YAxis Tick Render Issues

[alburdette619]

Fixed a few issues with the Y-Axis:

Provide ticks length to formatLabel - Allows users to know the number of ticks that result from d3. The y.ticks function isn't guaranteed to return the specified number of ticks. Without feedback, the user doesn't know how many ticks will be displayed.

Fix inconsistent tick re-render - Using an index for a key in RN is not advised, it does not provide a key that is maintainable and does not properly update each node. It's complicated but there are some very good write-ups on this. This lead to odd spacing despite y(value) returning proper values. The items simply weren't re-rendering.

More dynamic padding - The horizontal padding here adds on if the x value of the svg is set. Without this the text is cut off. I'm not sure this is the correct solution here but it works for my issues. Let me know if you have any advice on this. Reference #139

Would love to merge this as well. Just remove the formatting diffs and we're good to go!

@JesperLekland I've seen this on quite a few of my PRs, it seems there is linting built into the library and I have mine run automatically on save. I can cut it off, but shouldn't it be applied, or is it somehow being applied incorrectly by me?

Edit: Maybe it's my Prettier extension... :/
Nope, had it disabled for the workspace. I think this is just the installed eslint rules.

Hi Adam! As you might've noticed I haven't had that much time to maintain this library lately. I've invited you as a collaborator as you seem to have both the skill and interest to help make react-native-svg-charts the de facto chart library for RN. I would love for more people to get involved in this library and eventually growing into a full community.

@lavisht22 @JesperLekland Sorry to not get to this sooner. I wish I also had more time to help out here. As is I'm able to spend some time as I need it for work. More incoming 😄

Ugh, looks like we've been bitten by the Android license signing stuff...
