This class implement an Oid (Object Identifier).

An Oid is encoded as a list of bytes representing integers.

An Oid has a numeric representation where number are separated with dots :
SPNEGO Oid = 1.3.6.1.5.5.2

Translating from a byte list to a dot separated list of number follows the rules :
- the first number is in [0..2]
- the second number is in [0..39] if the first number is 0 or 1
- the first byte has a value equal to : number 1 * 40 + number two
- the upper bit of a byte is set if the next byte is a part of the number
For instance, the SPNEGO Oid (1.3.6.1.5.5.2) will be encoded :
```
 1.3 -> 0x2B (1*40 + 3 = 43 = 0x2B) .6  -> 0x06 .1  -> 0x01 .5  -> 0x05 .5  -> 0x05 .2  -> 0x02 
```
The Kerberos V5 Oid (1.2.840.48018.1.2.2) will be encoded :
```
 1.2   -> 0x2A (1*40 + 2 = 42 = 0x2A) 840   -> 0x86 0x48 (840 = 6 * 128 + 72 = (0x06 | 0x80) 0x48 = 0x86 0x48 48018 -> 0x82 0xF7 0x12 (2 * 128 * 128 + 119 * 128 + 18 = (0x02 | 0x80) (0x77 | 0x80) 0x12 .1    -> 0x01 .2    -> 0x02 .2    -> 0x02 
```
