No warning when analysis sr and fft sr differ

[Gautzilla]

Running an analysis like this:

analysis = Analysis(
    analysis_type=AnalysisType.SPECTROGRAM,
    begin=Timestamp("2023-04-05 16:45:00"),
    end=Timestamp("2023-04-05 17:00:00"),
    data_duration=Timedelta(seconds=10),
    sample_rate=32_000,
    fft=ShortTimeFFT(hamming(1024), 128, fs=48_000),
)

where the sample_rate and the ShortTimeFFT.fs differ should raise a warning, or even an exception.

Moreover, if the analysis have both AUDIO and SPECTROGRAM (or any spectral) export, the linking will raise an exception anyhow, so we'd rather raise an exception at the very beginning.
