* Computes the [[link-eip-191]] personal-sign message digest to sign.

* If %%message%% is a string, it is converted to its UTF-8 bytes

* to [bytes](getBytes).

* @example:
* hashMessage("Hello World")

* // Hashes the SIX (6) string characters, i.e.
* // [ "0", "x", "4", "2", "4", "3" ]
* hashMessage("0x4243")
* //_result:

* // Hashes the TWO (2) bytes [ 0x42, 0x43 ]...
* hashMessage(getBytes("0x4243"))

* // ...which is equal to using data
* hashMessage(new Uint8Array([ 0x42, 0x43 ]))
