Allow to customize colors of voice recording composer

[f3dm76]

What are you trying to achieve?

I need to replace this blue color with my custom color

I can see this .blue hardcoded here

/// The colour of the waveform bar that isn't part of the "played" duration.
open var barColor: UIColor { colors.textLowEmphasis }

/// The colour of the waveform bar that is part of the "played" duration.
open var highlightedBarColor: UIColor { .blue }

/// The colour of the waveform bar's background.
open var barBackgroundColor: UIColor { colors.background }

Could you please use a theme color for this?
