[BUG] 'static lifetime requirement for ChartContext

[DoomDuck]

Describe the bug
I wanted to increase the size of the labels but got a lifetime error.
I haven't found a workaround, nor the cause of the error.

However, this looks similar to #62

To Reproduce

use plotters::{backend::SVGBackend, prelude::*};

fn main() {
    let root = SVGBackend::new("plot.svg", (1920, 1080)).into_drawing_area();

    let mut chart = ChartBuilder::on(&root)
        .build_cartesian_2d(0..1, 0..1)
        .unwrap();

    // Using `label_style` results in chart being borrowed for 'static
    chart.configure_mesh().label_style(24);
}

Compiler output

error[E0597]: `chart` does not live long enough
  --> src/main.rs:11:5
   |
6  |     let mut chart = ChartBuilder::on(&root)
   |         --------- binding `chart` declared here
...
11 |     chart.configure_mesh().label_style(24);
   |     ^^^^^-----------------
   |     |
   |     borrowed value does not live long enough
   |     argument requires that `chart` is borrowed for `'static`
12 | }
   | - `chart` dropped here while still borrowed

Version Information
The behavior is present on 0.3.6 which is the current state of master
Rust version: 1.78.0

In the following part of the code, changing the 'static lifetime parameters to 'a appears to solve the problem.
