[Feature Request] Allow user to tweak spacing of CPU vertical bars

[n-6]

When using MenuMeters to independently display all CPU cores in the Vertical bar format, the CPU bars are separated by a fair amount of white space. On my MacBook Pro 14 with 10 CPU cores, this takes up lots of menu bar real estate, especially with the notch reducing the total available space.

It would nice to be able to reduce the whitespace between the vertical bars so that this display mode takes up less space on high CPU core count machines. The Horizontal bar format does take up less space, but I prefer the look of the vertical bars and want to keep the per-CPU vs average or sum options.
