Incorrect Extra Values in AB Data

[rbrtschwn]

Hi,

First of all, thank you for providing this library!

While trying it, we have come across an issue when reading AB spectra. There are extra values that OPUS does not show. I believe this is related to this comment in the source code: https://github.com/qedsoftware/brukeropusreader/blob/ed13492490dcbdc3b66aefa503e81f112b8df481/brukeropusreader/opus_data.py#L10

This comment suggests that the actual number of y data points may be larger than what the NPT parameter says, so extra x values are added accordingly. Probably, it should be the other way around. NPT is correct and extra y values should be truncated.

Any chance of changing the behavior?
