Analysis overwrite protection

[Gautzilla]

This PR introduces a ValueError raising when attempting to run an analysis which has already been ran:

dataset.run_analysis(
    Analysis(
        analysis_type=AnalysisType.AUDIO,
        data_duration=dataset.origin_dataset.duration / 10,
        name="my_analysis",
        sample_rate=24_000,
    )
)

"""
RUNNING THIS WOULD NOW RAISE AN ERROR
dataset.run_analysis(
    Analysis(
        analysis_type=AnalysisType.SPECTROGRAM,
        data_duration=dataset.origin_dataset.duration / 10,
        name="my_analysis",
        sample_rate=24_000,
        fft=ShortTimeFFT(hamming(1024), hop=1024, fs=24_000),
    )
"""

# We can either rename the analysis or delete the previous one:
dataset.delete_analysis("my_analysis")

dataset.run_analysis(
    Analysis(
        analysis_type=AnalysisType.SPECTROGRAM,
        data_duration=dataset.origin_dataset.duration / 10,
        name="my_analysis",
        sample_rate=24_000,
        fft=ShortTimeFFT(hamming(1024), hop=1024, fs=24_000),
    )
)

Renaming an analysis

Analyses can be renamed easily. All corresponding folders and files will be moved accordingly:

dataset.rename_analysis("my_analysis", "my_new_analysis")

Dataset would need a rename method as well
