Write ConvertTo-SnakeCase so it converts PascalCase or camelCase text to snake_case.

Acronyms stay together.

    ConvertTo-SnakeCase 'HelloWorld'        # hello_world

    ConvertTo-SnakeCase 'getHTTPResponse'   # get_http_response

    ConvertTo-SnakeCase 'already_snake'     # already_snake

'@

        '-replace is case-INSENSITIVE, so [A-Z] matches lowercase too. Use -creplace.'

        'Lookarounds match a position without consuming characters: (?<=[a-z0-9])(?=[A-Z]) is the gap between a lowercase letter and an uppercase one.'

        'Acronyms: the gap in "HTTPResponse" sits between the P and "Re", so (?<=[A-Z])(?=[A-Z][a-z]). Lowercase at the end.'
