[Feature] Add format_units_with

[mattsse]

Component

primitives

Describe the feature you would like

we format units like:

core/crates/primitives/src/utils/units.rs

Lines 245 to 248 in 74717c0

	/// Formats the given number of Wei as the given unit.
	///
	/// See [`format_units`] for more information.
	pub fn format_units(&self, mut unit: Unit) -> String {

only supporting .:

core/crates/primitives/src/utils/units.rs

Line 263 in 74717c0

format!("{integer}.{decimals:0>units$}")

it would be nice if we can support locale settings, but we only need "." and "," here really.

we can make this work with a helper enum, like enum DecimalSeparator {Command, Period}

TODO

• introduce a new fn that accepts this helper type
• refactor existing fn so that this simply calls format_units_with(..., DecimalSeparator::Period)
