Reads a list as a one-dimensional array of decimals.
The expression does not need to have head List. In other words, it could be Foo[1.0, 2.0]. The information about the head is lost; if you need this information you can either use GetArray(Type leafType, int depth, out string heads), or read the expression as an Expr and examine it using the Expr methods.
