Unable to override default delimiter processors

Is your feature request related to a problem? Please describe.
I wish to override the default delimiter processors the sake of better supporting Discord's markdown quirks. However, I am left unable to override the default options without an exception being thrown due to conflicting characters.

Describe the solution you'd like
I would like to be able to override the two default delimiter processors with my own implementations of the two somehow within the Parser builder.

Describe alternatives you've considered
The current solution for this is to copy the InlineParserImpl class and make your modifications to it, which is definitely not ideal.

从 Parser builder 和 InlineParserImpl 开始，重点了解两个默认 delimiter processor 是如何注册的，以及冲突字符是如何验证的。跟踪现有的选项注册路径，并确定自定义实现如何在不触发冲突异常的情况下替换这些默认实现。完成标准是 builder 接受这两个覆盖实现，并且 Discord 风格的 delimiter 行为由测试覆盖。
