Support different numeric types

[TonyGravagno]

MySQL has tinyint(n), smallint, bigint, float, double, etc. All of these are represented as z.number() in mysql-zod.

Add support for at least a few of the more common numeric types. Examples to enforce min, max, etc:

z.coerce.number() // Force it to be a number
  .int() // Make sure it's an integer
  .gte(10000) // Greater than or equal to the smallest 5 digit int
  .lte(99999) // Less than or equal to the largest 5 digit int
...
  someNumber: z.string().transform((val) => {
    if (val.length !== 5) ... different ways to handle issue ...
    return parseInt(val, 10)
  }),
