Scalar parsing library

Scalar is a library for parsing strings into arbitrary scalars (integers, floats, strings, booleans, etc). It is helpful for tasks such as parsing strings passed as environment variables or command line arguments.

The main API works as follows:

var value int
err := scalar.Parse(&value, "123")

There is also a variant that takes a reflect.Value:

var value int
err := scalar.ParseValue(reflect.ValueOf(&value), "123")
