|jdk1.6.0_45| "UTF-8"| StringRead: | 34721 ms |      1.152|        41.032|       1780910|
|jdk1.6.0_45| Charset| StringRead: | 45231 ms |      0.884|        31.499|       1780910|

> AVRO-1241 found that the existing method of creating Strings from Utf8 byte arrays could
be made faster. The same method is being used in the Utf8.toString(), and could likely be
sped up by doing the same thing.
