Description
cast max uint32 string to uint32:
cast.ToUint32E("4294967295") returns 0 and err: unable to cast "4294967295" of type string to uint32
cast max uint64 string to uint64:
cast.ToUint64E("18446744073709551615") returns 0 and err: unable to cast "18446744073709551615" of type string to uint64
The cases above work fine in v1.4.1.

Research direction
Start by reproducing the two cast.ToUint32E and cast.ToUint64E calls on arm32, then compare their behavior with v1.4.1. Trace the string-to-integer conversion path and verify that both maximum unsigned values cast successfully without an error.
