Invalid encoding and decoding of OIDs

[zaczkows]

Hello,
This crate is amazing and speeds up my small ASN.1 encoding project enormously :-)

However, I found a bug when encoding OIDs, having values bigger than 127. E.g. when taking following example ID from MS website encoding using rasn gives back:

• wrong [2b, 6, 1, 4, 1, b7, 2,15,14] (this actually decodes to 1.3.6.1.4.1.7042.21.20, look here)
• instead of correct [2b, 6, 1, 4, 1, b7, 2, 15, 14]

Another example is from stackoverflow and 1.2.840.113549.1.1.5 (sha1WithRsaEncryption):

• current (incorrect) encoding: [2a, c8, 6, 8d, f7, 6, 1, 1, 5] (lapo.it)
• correct encoding: [2a, 86, 48, 86, f7, d, 1, 1, 5] (lapo.it)

BR, Piotr
