[nit] The memory usage comparisons in the README are inaccurate

[jussi-kalliokoski]

There are some highly confusing memory consumption comparisons in the README. For example https://github.com/golangci/golangci-lint/blame/master/README.md#L136 states the following:

consumes 1.35x less memory

Assuming that x is the memory consumption, and golangci-lint consumes 1.35x less memory, it would mean x - 1.35x = -0.35x, so golangci-lint consumes negative memory? I'm exaggerating of course, but I really am not sure what 1.35x less memory means. My best guess is that the intended meaning is that for every 1.35GB that metalinter consumes, golangci-lint consumes 1GB? If that's the case, I suggest using 1 - 1.00GB / 1.35GB ~= 0.259 so golangci-lint uses 26% less memory, using multipliers when talking about decreased values is bound to lead to confusion.

Yes, I'm fun at parties.
