Tynm -- Type Name

Returns type names with a specifiable number of module segments as a String.

```rust

[rustfmt::skip]

asserteq!( std::any::typename::>(), "core::option::Option" );

[rustfmt::skip]

let tuples = vec![ (tynm::typename::>(), "Option"), (tynm::typenamem::>(1), "core::..::Option"), (tynm::typenamen::>(1), "..::option::Option<..::string::String>"), // 1 segment from most and least significant modules. (tynm::typenamemn::(1, 1), "rustout::..::three::Struct"), // traits (tynm::typename::(), "dyn Debug"), ];

tuples .iter() .foreach(|(left, right)| asserteq!(left, right));

```

Motivation

The [std::any::type_name] function stabilized in Rust 1.38 returns the fully qualified type name with all module segments. This can be difficult to read in error messages, especially for type-parameterized types.

Often, the simple type name is more readable, and enough to distinguish the type referenced in an error.
