Parse the given text into a number instance of the given target class,
using the corresponding default <code>decode</code> methods. Trims the
input <code>String</code> before attempting to parse the number. Supports
numbers in hex format (with leading 0x) and in octal format (with leading 0).

@param text        the text to convert
@param targetClass the target class to parse into
@return the parsed number
@throws IllegalArgumentException if the target class is not supported
(i.e. not a standard Number subclass as included in the JDK)
