Strings (phase I)

[ArielElp]

In the first phase, we will add byte arrays to the language.

Users will be able to initialize byte arrays via a syntax similar to let err = b"this is a long error string".

Byte arrays answer many of the standard blockchain use of strings, such as storing constant URLs in a contract. Additionally, asserts will now be able to pass byte arrays that encode an ASCII string rather than a short string (31 bytes) which is usually not enough to describe the error.

We will introduce a String type supporting standard string operations in the second phase. Under the hood, it will be implemented with byte arrays.
