ARROW-11653: [Rust][DataFusion] Postgres String Functions: ascii, chr, initcap, repeat, reverse, to_hex @alamb This is the second last of the current string functions but I think there may be one after that with new code. This implements some of the miscellaneous string functions `ascii`, `chr`, `initcap`, `repeat`, `reverse`, `to_hex`. The next PR will have more useful functions (including regex). A little bit of tidying for consistency to the other functions was applied. This PR is a child of #9243 Closes #9625 from seddonm1/ascii-chr-initcap-repeat-reverse-tohex Authored-by: Mike Seddon <seddonm1@gmail.com> Signed-off-by: Andrew Lamb <andrew@nerdnetworks.org>
