[BUG] min validation evaluates string as number

[grischaerbe]

The min validation evaluates strings that represent numbers (e.g. '1234') against their numeric value.

This field:

export const password = field('password', '', [required(), min(8)])

With this input: '8' evaluates to valid. Evaluation here.
I didn't test it but it seems max is different and is accounting for that.

Sorry, seems to be a duplicate of #88, can be closed if needed.

I have a possible solution in #118
