Add config checks

[Skealz]

Example :

from typing import List, Optional, Dict, Union
from pydantic import BaseModel, EmailStr, Field, HttpUrl, ValidationError
import yaml
import os

class Config(BaseModel):
    processor: str
    conda_executable: str
    l2plugins: List[str]
    chain_topdir_data: str
    conda_env_base_path: str
    processing_subdir: str
    report_subdir: str
    listing_subdir: str
    configs_directory: str
    grdwind_config_file: str
    l2_status_subdir: str
    l2_status_filename: str
    l2c_status_filename: str
    l2m_res: List[int]
    postproc_subdir: str
    envs: Dict[str, List[EnvItem]]
    conda_channels: List[str]
    symlink_plugin_l2: Optional[List[Dict[str, List[int]]]]
    symlink_plugin_l2c: Optional[List[Dict[str, List[int]]]]
    symlink_plugin_l2m: Optional[List[Dict[str, List[int]]]]
    reduce: Dict[str, Reduce]


def validate_load_yaml(file_path: str):
    with open(file_path, "r") as file:
        data = yaml.safe_load(file)
        config = Config(**data)
        return config

This can be used to specified expected types and even allowed/default values for the config. This helps warn the user if a wrong value is given. See pydantic documentation for more details.
