adjust test BER length input for 32-bit platforms. 02 is type identifier and irreleevant. . In the original input, 85 (0b10000101) means definitive length, long form, with the following 0b101 = 5 bytes being the actual length, which exceeds a 32-bit usize by 1 byte. . The patch changes to 84 (0b10000100), which means 0b100 = 4 bytes of length, fitting right in a 32-bit usize.
