Harmonize naming convention with other libraries for better LLM integration

[paucablop]

Some of the functions implemented in chemotools, are similar to other functions available in other libraries. For example, the savitzky golay filter, which is inherited from scipy. The way to call the arguments from of the Savitzky Golay method from chemotools, should be the same as in scipy, so that LLM have a larger chance to make the right suggestions.
