add dbt_ml_inline_preprocessing

Description

This package allows users to perform common machine learning preprocessing techniques inline with their SQL select statements, only requiring model references when absolutely required.

Techniques that can be performed inline include:

categorical imputation
numerical imputation
random imputation
label encoding
one hot encoding
rare category encoding
interaction terms
k bins discretization
log transformation
max absolute value scaling
min/max scaling
numerical binarization
robust scaling
standardization

This allows for those doing their machine learning preprocessing in dbt to do so in a more semantically followable, interchangeable, and flexible fashion

Checklist

This checklist is a cut down version of the best practices that we have identified as the package hub has grown. Although meeting these checklist items is not a prerequisite to being added to the Hub, we have found that packages which don't conform provide a worse user experience.

First run experience

[X] (Required): The package includes a licence file detectable by GitHub, such as the Apache 2.0 or MIT licence.
[X] The package includes a README which explains how to get started with the package and customise its behaviour
[X] The README indicates which data warehouses/platforms are expected to work with this package

Customisability

[X] The package uses ref or source, instead of hard-coding table references.
Packages for data transformation (delete if not relevant):
[X] provide a mechanism (such as variables) to customise the location of source tables.
[X] do not assume database/schema names in sources.

Dependencies

Dependencies on dbt Core

[X] The package has set a supported require-dbt-version range in dbt_project.yml. Example: A package which depends on functionality added in dbt Core 1.2 should set its require-dbt-version property to [">=1.2.0", "<2.0.0"].
Dependencies on other packages defined in packages.yml:
[X] Dependencies are imported from the dbt Package Hub when available, as opposed to a git installation.
[X] Dependencies contain the widest possible range of supported versions, to minimise issues in dependency resolution.
[X] In particular, dependencies are not pinned to a patch version unless there is a known incompatibility.
Interoperability
[X] The package does not override dbt Core behaviour in such a way as to impact other dbt resources (models, tests, etc) not provided by the package.
[X] The package uses the cross-database macros built into dbt Core where available, such as {{ dbt.except() }} and {{ dbt.type_string() }}.
[X] The package disambiguates its resource names to avoid clashes with nodes that are likely to already exist in a project. For example, packages should not provide a model simply called users.

Versioning

[X] (Required): The package's git tags validates against the regex defined in version.py
[X] The package's version follows the guidance of Semantic Versioning 2.0.0. (Note in particular the recommendation for production-ready packages to be version 1.0.0 or above)
