Upgrade Iced to 0.13

[fazibear]

My attempt to upgrade iced version to 0.13.

Widgets are working. I'm almost there. Few things are missing.

What is missing?

• text/tick marks cache
• mod ranges don't work as expected (also in old version)
• proper text bound in rendering text marks
• some unwraps left

Marks Cache

Why there is custom cache solution? Maybe just use iced build in Cache?

PS. This is just a PR, all my work is here: https://github.com/fazibear/iced_audio_0.13

I just ran examples on FreeBSD, and they almost all work. The two that didn't work have a small typo:

1. examples/h_slider.rs imports widget::h_slider::HSlider instead of h_slider::HSlider
2. examples/ramp.rs imports widget::ramp::RampDirection instead of ramp::RampDirection

That being said, can I help in any way other than testing on my machine?
