build: relax dependencies

[QuadnucYard]

Changes in Cargo.toml

• Reduce the minimum version requirement of dependencies. memchr can have no default features.
• (breaking) Move dependencies unrelated to functionality (log, serde_json, tempfile) to dev-dependencies.

Related changes about function only covered in tests are not done yet.

Questions about deps and more changes

I found most macros are not necessary for this serde of yml. Could they be just removed, added feature flags, or moved to another crate?

• macro_directory, macro_file, macro_get_field: Could be moved to a utility crate, as they depend on filesystem and different serde formats. Besides, the Not Found error message checking in tests can fail where it is not given in English.
• macro_nested_enum_serde. Just a one-line shorthand.
• macro_replace_placeholder. It does nothing with yml. Just a string utility.
• macro_from_number. It may be replaced by a blanket impl:

  impl<T> From<T> for Value
  where
      T: Into<Number>,
  {
      fn from(n: T) -> Self {
          Value::Number(n.into())
      }
  }

  macro_partialeq_numeric does more, but it does not need to be exported either.
• crate::utilities::directory is only referer in fs related tests. It should belong to a fs utility crate. dep::tempfile and dep:log go with it.
• serde_yml::modules::path::Path derives Serialize only because a test need it. If this derive is stripped, dep:serde can have no extra feature enabled.
• anyhow only appears in docs. serde_yml::Result<()> is adequate here.
• It is surprising that serde_json is a dependency in a yml library.

A radical patch can be found in https://github.com/QuadnucYard/serde_yml/tree/relex-deps-radical. I do not include it here.

btw, could you open the issues channel?

@QuadnucYard Many thanks for your updates and changes.

I have implemented it in the next release PR, I removed the macros and merged your radical patch.
