Feat/init_from_path

[Zeyi-Lin]

Description

1. 支持通过json/yaml配置文件初始化swanlab.init，接口为swanlab.init_from_path
2. 删除正则表达式

测试脚本：

import swanlab

run = swanlab.init_from_path('.../swanlab-config.yaml')

for epoch in range(2, run.config.epochs):
    acc = 1 - 2**-epoch - random.random() / epoch - offset
    loss = 2**-epoch + random.random() / epoch + offset
    print(f"Epoch {epoch}: loss={loss}, accuracy={acc}")
    swanlab.log({"loss": loss, "accuracy": acc})

配置文件：

experiment_name: 🙋Hello World
description: 你好，世界
config:
  epochs: 10
  learning_rate: 0.0001
