This commit removes all the old casting/generic traits from `std::num` that are no longer in use by the standard library. This additionally removes the old `strconv` module which has not seen much use in quite a long time. All generic functionality has been supplanted with traits in the `num` crate and the `strconv` module is supplanted with the [rust-strconv crate][rust-strconv]. [rust-strconv]: https://github.com/lifthrasiir/rust-strconv This is a breaking change due to the removal of these deprecated crates, and the alternative crates are listed above. [breaking-change]
