Just to explain the diff noise in this file:
There was already this Skipping around data test block that had tests manipulating the readOffset to skip. I replaced this block's tests with ones for readSkip/writeSkip, and moved the old tests* to the Setting write and read offsets block, since that felt like the more appropriate place for them.
* Actually, in the case of the Should throw an error when attempting to skip more bytes than actually exist test, I removed it completely because you already had other tests that covered it.

Originally I had this so that it would be more similar to writeSkip:
| this.readOffset += length; | |
| this.readBuffer(length); // Ignore the returned buffer value |
But it did not throw an error if length went beyond the bounds of the buffer, so I changed it.
Let me know if you would prefer it to not throw an error though.
This PR adds convenience methods for skipping when reading/writing.
Resolves #46.
