_times reserved parameter can be non numeric

[dcroote]

To verify, the value below can be changed to a non-number and the tests still pass

ois/test/fixtures/ois.json

Lines 74 to 75 in f03d5ad

	"name": "_times",
	"default": "1000000"

Validating this is slightly complicated by multiple reserved parameters e.g. _times: ',10000,', but it still should be attainable after splitting using transform and something like:

export const stringifiedNumberSchema = z.string().transform((val) => parseFloat(val));

Yeah, none of the reserved parameter values is actually validated as we only verify that the value is a string type.
