Description
In the calculation of recurrence matrices with fixed recurrence rate there is the issue commented in #46 (indirectly calling distancematrix, which is expensive):
A function that gives the same result as quantile(distancematrix(x,y), ε) without calling distancematrix would help.

Research direction
Start at src/matrices.jl around lines 220-222 and read issue #46 for the fixed-rate calculation context. Compare the current indirect distancematrix path with the target quantile(distancematrix(x,y), ε) result. Done means fixedrate=true produces the same result without calling distancematrix and improves the calculation's performance.
