Add more info about high-wavenumber filtering in FilteredTimeSTeppers

[navidcy]

We need to include include more information about the exponential filtering. E.g.,

• what the exponentional filtering tries to achieve
• how is the cutoff wavenumber computed
• how is the coefficient exponent computed
• refer to Arbic & Flierl 2003 (or possibly also to LaCasce 1996, Canuto et al. 1988) where this exponential wavenumber filtering originates

Just spotted a minor typo: https://fourierflows.github.io/FourierFlowsDocumentation/previews/PR353/timestepping/ Given the order p, we calculate the coefficient α so that the *the* filter value that corresponds to the highest allowed wavenumber in our domain is a small value, δ, taken to be close to machine precision. The appears twice in the above sentence (in bold).
