bar with customized width

[njuFerret]

When using a bar graph as an indicator, such as for PWM's duty ratio, it can be challenging to draw the graph at a specific position and width. Modifications has been made in the source code to implement such a scenario.

Forgot to add a macro to keep compatibility
#define MUIF_U8G2_U8_MIN_MAX_STEP(id, valptr, min, max, step, flags, muif) MUIF_U8G2_U8_MIN_MAX_STEP_WIDTH(id, valptr, min, max, step, max, flags, muif)

the macro patch, as well as value with boundary in mui_u8g2_u8_bar_wm_mse_pf function.

So the "width" argument is the total width of the bar graph.
I also think that the scale argument is kind of obsolete, because we could just multiply width with 2 or 4 instead.
All in all I more think about creating a second bar graph instead of updating the existing one.

One more doubt: You have disabled the wrap around to the min value. This would be fine for the "mud" edit mode, but would be an issue with the "mse" edit mode. Instead we should have an option here instead of hard coding this. I think your PR addresses multiple problems, which should be fixed independently.

a rotary encoder was employed for user input, where mse mode isn't the candidate. therefore, the modification was not been tested. I think it's a good idea provide user some options to do that.

ye, "max" used as total width of bar graph, was replaced by "width" argument. The "scale" arg maybe useful for large display, due to "width" defined as "uint8_t".

I have recreated a new field function instead: https://github.com/olikraus/u8g2/wiki/muiref#fixed-width-bar-graph-uint8

So closing this PR without merge.

awesome!
