Feature: String starts/ends with

[alii]

I was writing a validator for a hex color code and thought that being able to check that it started with a # would be a nice addition.

E.g.: z.string().length(7).startsWith('#')

You can already do that:

z.string().length(7).regex(/^#/);

Even though this is doable with regexes, it's also a one-line addition to ZodString so I'm fine adding it into core. PR welcome 👍

An updated version if you need supporting 3 and 8 digit hex too

color: z.string().min(4).max(9).regex(/^#/),
This allows for
#FFF (White, simplified, it just becomes #FFFFFF)
and #FFFFFF80 (White, with 80% transparency)

in case helps anyone looking for this
