1G1R do not fetch all the candidates before filtering

Hi, I cannot understand why the single option writes multiple files on certain parent/clones relations.

@R1nlz3r because you're using the No-Intro "standard" DATs and not the "P/C" DATs per https://igir.io/dats/introduction/#parentclone-pc-dats.

That said, Igir should be able to support this non-standard format.
