Make slight changes to bit timings so the library will work with these popular LED string https://www.ebay.co.uk/itm/373588834942?var=642594617777

I have tried many libraries but all fail

I do have logic analyzer screen shots attached and here are the timings

T1H 320ns
T1L 1.28us
T0H 1.12us
T0L 480ns

it does have a 9.12us gap between LED packets, I can provide the actual capture file and you an download the free Saleae software to view it.

happy to pay to have a one off library or contribute if it becomes part of the main library
