Configure enabeld and options of encodingDetectors

[304NotModified]

To prevent false positives or results that aren't usage

Example 1: prefer utf8 over ascii Example 2: disable non western style encodings Example 3: detect utf16 without bom

Idea, users could:

• configure list of probers, there is a default list
• weight of probers and/or ordening of probers
• options of a prober, e.g. 60% 0 values on 2 bytes is a utf16 without bom
