保存水印参数：
$ textwatermark -v insert -f './tests/text/number.txt' -m ALPHA_NUMERICAL -t HOMOGRAPH_NUMBERS -x 999 -w 123 -e
{"tpl_type": "HOMOGRAPH_NUMBERS", "confusables_chars": [], "confusables_chars_key": "", "wm_base": 7, "method": 1, "wm_mode": 5, "wm_len": 7, "wm_loop": false, "start_at": 0, "version": "0.1.2"}
从文本提取水印：
$ textwatermark -v retrieve -f out.txt -p '{"tpl_type": "HOMOGRAPH_NUMBERS", "confusables_chars": [], "confusables_chars_key": "", "wm_base": 7, "method": 1, "wm_mode": 5, "wm_len": 7, "wm_loop": false, "start_at": 0, "version": "0.1.2"}'
The retrieved watermark is: 123
