Float Param min_value incorrectly enforced

[R4chel]

If I set a param
foo = vsketch.Param(0.3, min_value=0.001)
In the gui, I am able to set foo to 0

I didn't come across it until looking into this but there is a symmetrical problem for max_value

I came across this because I wanted to avoid division by zero errors, so I wanted to prevent some values from being 0. I wanted to do it in a generalized way so that I wouldn't have to change depending on how many the decimals parameter so I set the value to 1e-10 and found I was still able to set the parameters to 0 and run into the division by zero error.

I dug into this a little bit I believe rounding is happening somewhere because for example in the case where decimals=1

foo = vsketch.Param(0.3, decimals=1, min_value=0.05) -> stops foo from being
foo = vsketch.Param(0.3, decimals=1, min_value=0.049) -> allows the foo to be set to 0.
