 So turn out that the constants mentioned in this paper are not wrong they are for specific stages and alpha

@ChrisRackauckas This could be a bigger issue because know we have to calculate the constants and it will not be a trivial task.

Should probably move this to #73

@ranocha These papers [Kubatko, Yeager, Ketcheson (2014)](https://link.springer.com/article/10.1007%2Fs10915-013-9796-7) and [Kennedy, Carpenter, Lewis (2000)](https://www.sciencedirect.com/science/article/pii/S0168927499001415) have 21 and >16 schemes respectively. We might not want to implement all of them. But I'm not...
