Dynamic segment sizing

[maxcampolo]

This PR adds support for dynamic segment sizing based on the content size of the segment. Instead of fixing the number of visible cells, each cell is a different size based on the length of its title (plus the image in the case of the imageBefore and imageAfter styles). The way to use it is to pass a SegmentioPosition option in the initializer, either .dynamic or .fixed(maxVisibleItems: 3). The fixed option is the same behavior that exists currently.
Changes:

• Add SegmentioPosition enum with fixed and dynamic options
• Replace maxVisibleItems with maxVisibleItems property in fixed case eg. .fixed(maxVisibleItems: 3)
• Update Points extension with more parameters for dynamic layout calculations
• Replace scrollToItem at index path calls with scrollRectToVisible in scrollToItemAtContext
• Update itemInSuperview method for dynamic and fixed position cases
• Separated method for calculating segment width
• Added width property to SegmentioItem
• Update example project

There are quite a few changes in this PR so if you want anything updated, changed, done differently, etc. please let me know and I’m happy to do it!

Ty for the awesome framework.

Hey @rmvz3 all these changes are in the branch called fix/label-layout. I'll just merge it over to my master eventually but you can use that branch for now.

@maxcampolo I've just realized. That's why I deleted my question. My fault ¯_(ツ)_/¯

Thank you

Hello @maxcampolo , thank you for a great work. I have tested your PR and found some issues with cell width

and also with wrong positioning of indicator

Can you fix them?

[maxcampolo]

@Tykhonkov sure thing let me look at this. The first image looks correct, the cell sizes based on the size of the content contained in it, using the image width if there is no label. The second image indicator position is definitely wrong. Any specifics on reproducing? Thanks!

[maxcampolo]

@Tykhonkov I pushed some updates that should fix these issues. I also updated the example project so to test you can just add the segmentioPosition: .dynamic option to the SegmentioBuilder call in ViewDidAppear(_:) of ExampleViewController.

Thanks for reviewing!

[Tykhonkov]

i'll test it

Apologies for bothering, but may I ask if this PR is going to be merged any time soon?
I'll just use the specific branch for now in any case

@maxcampolo Could you please update your request by pulling last changes in our master branch ?

[maxcampolo]

@AndrewPetrov okay I've merged the latest from master and updated the PR. Thanks for reviewing!

@maxcampolo I'm sorry but your fix still has some issues with highlighting
It appears when you tap half-hidden most right cell

@AndrewPetrov sorry about that! This was just a bug calculating the position in the .fixed segment width option. Turned out to be misplaced if statement brackets. Should be fixed now. Thanks!
