Add optional gauges for effects that accumulate.

Hi,

While playing with this mod (version 0.11.2), I found the Roller Skate, and having the extra speed early on is really nice for getting around, but the field of view changes caused by having the speed bonus cap at 85% were causing me to feel a bit sick, so I turned FOV Effects off in my accessibility settings, and not long after I noticed that the FOV change was the only indicator for how much speed Roller Skate was providing at a given moment.

I am suggesting that relics with a build-up mechanic (such as the speed increase from Roller Skate) brings up a bar on the HUD that indicates how much additional speed (and reduced friction) that the player has, something akin to the P-Speed meter in Super Mario Brothers 3.

Thank you for making this mod, too.
