New anomaly: Normalize

[SebastianSchmidl]

Normalization anomalies can be constructed by combining mean and amplitude anomaly kinds, however, this is difficult to achieve. Add a new anomaly kind that allows to specify the way a subsequence should be normalized. Normalization options:

• normalize-z
• normalize-minmax
• normalize-median
• normalize-mean
• normalize-logistic
• normalize-tanh

Example configuration:

timeseries:
  - name: "test"
    base-oscillations:
      - kind: "sine"
    anomalies:
      - position: beginning
        length: 100
        kinds:
          - kind: "normalize-minmax"
            min: 0
            max: 1
