cryptobyte: fix panic due to malformed ASN.1 inputs on 32-bit archs When int is 32 bits wide (on 32-bit architectures like 386 and arm), an overflow could occur, causing a panic, due to malformed ASN.1 being passed to any of the ASN1 methods of String. Tested on linux/386 and darwin/amd64. This fixes CVE-2020-7919 and was found thanks to the Project Wycheproof test vectors.
