Initialize the Item for receiving progress information.
If `max` is `Some(…)`, it will be treated as upper bound. When progress is set(…) it should not exceed the given maximum. If `max` is `None`, the progress is unbounded. Use this if the amount of work cannot accurately be determined in advance.
If `unit` is `Some(…)`, it is used for display purposes only. See `prodash::Unit` for more information.
If both `unit` and `max` are `None`, the item will be reset to be equivalent to ‘uninitialized’.
If this method is never called, this `Progress` instance will serve as organizational unit, useful to add more structure to the progress tree (e.g. a headline).
**Note** that this method can be called multiple times, changing the bounded-ness and unit at will.

### Parameters
- **max** (Option<Step>) - Description: The maximum value for the progress, or None if unbounded.
- **unit** (Option<Unit>) - Description: The unit for display purposes, or None.

Return the level at which this sibling is located in the hierarchy.

#### pub fn get(&self, level: Level) -> Option<&SiblingLocation>
Get a reference to the sibling location at `level`.

### Struct Options

Source: https://docs.rs/prodash/31.0.0/prodash/render/line/struct.Options.html

Represents the configuration options for the line renderer.

```APIDOC
## Struct Options

### Description
Options used for configuring a line renderer.

### Fields
- **output_is_terminal**: `bool` - If true, assumes the output stream belongs to a terminal. If false, no live progress is printed, only log messages.
- **colored**: `bool` - If true, displays color. Should be determined by `output_is_terminal && crosstermion::should_colorize()`. Can be enforced even if the output stream is not connected to a terminal.
- **timestamp**: `bool` - If true, a timestamp will be shown before each message.
- **terminal_dimensions**: `(u16, u16)` - The amount of columns and rows to use for drawing. Defaults to (80, 20).
- **hide_cursor**: `bool` - If true, the cursor will be hidden for a more visually appealing display. Ensure proper shutdown to restore cursor settings.
- **throughput**: `bool` - If true, tracks previous progress state to derive continuous throughput information. Throughput is opt-in for units and incurs additional memory and CPU cost.
- **level_filter**: `Option<RangeInclusive<Level>>` - If set, specifies all levels that should be shown. Otherwise, all available levels are shown. Useful for filtering out high-noise lower-level progress items.
- **initial_delay**: `Option<Duration>` - If set, progress will only be shown after the given duration. Log messages are always shown without delay. Useful to avoid flickering for short actions.
- **frames_per_second**: `f32` - The amount of frames to draw per second. If below 1.0, it determines the amount of seconds between frames (e.g., 1.0/4.0 is one frame every 4 seconds).
- **keep_running_if_progress_is_empty**: `bool` - If true, continues waiting for progress even after encountering an empty list of drawable progress items. Ensure at least one item is added to `prodash::Tree` before launching to avoid race conditions.
