Summary	08542: spec128, specpl3e: Some spectrum models are running at wrong speed
Description	Some spectrum models (Zx Spectrum 128 and Zx Spectrum +3) are running a little bit faster (50.021154 Hz) than they should, according to this link: https://worldofspectrum.org/faq/reference/128kreference.htm "Note that this means that there are 70908 T states per frame, and the '50 Hz' interrupt occurs at 50.01 Hz, as compared with 50.08 Hz on the 48K machine."
Steps To Reproduce	Launch one of those spectrum models: -spec128 -specpl3e
