ModifierReverse causes characters to become clear in Gauge

## Description
When gauge cells reach the label they (both gauge cells and label) become totally transparent


## How to reproduce
- Create a gauge with any style
- Set percentage to >48%

## Additional
- Shells:
- fish
- zsh
- bash
- Color scheme:
- sweet-mars
- breeze
- linux-dark
- Terminal emulators
- Terminator
- Alacritty
- Konsole
- Yakuake

Same behavior everywhere

## Possible solution
I figured out that these lines produce such behavior:
```go
if labelXCoordinate+i+1 <= self.Inner.Min.X+barWidth {
style = NewStyle(self.BarColor, ColorClear, ModifierReverse)
}
```
Removing **ModifierReverse** makes it normal (normal assuming we have already the wrong color calculation)
Removing **ModifierReverse** and swapping remaining parameters seems to almost fix the issue:
```go
if labelXCoordinate+i+1 <= self.Inner.Min.X+barWidth {
style = NewStyle(ColorClear, self.BarColor)
}
```


Label color is obviously not getting reversed, so a bad color combination will result in an unreadable label. However, I haven't dig into the mathematics behind reverse color calculation and I cannot assume it's a 100% **ModifierReverse** issue.

Start at the gauge rendering code containing the ModifierReverse and NewStyle snippet, then reproduce the issue with a gauge above 48% in a terminal. Trace the reverse-color calculation and compare the affected gauge cells and label. Done means the gauge and label remain visible with correct, readable colors across the reported terminal setups.
