feat(mapper): add generic MapDirect APIs - version 0.8

🚀 Version 0.8

⚡ Performance Optimization

• MapDirect 系列函数 - 新增函数式泛型 API，带字段映射缓存

方法	旧版本	新版本	提升
单次映射	3,897 ns/op	556 ns/op	7x
批量映射 (100条)	452,718 ns/op	59,185 ns/op	7.6x
内存占用	400 B/op	272 B/op	-32%
内存分配	42 allocs/op	4 allocs/op	-90%

✨ New APIs

• MapDirect[From, To](from From) To - 直接返回映射结果
• MapDirectPtr[From, To](from *From) *To - 指针版本
• MapDirectSlice[From, To](from []From) []To - 批量映射
• MapDirectPtrSlice[From, To](from []*From) []*To - 指针批量
• SafeMapDirect[From, To](from From) (To, error) - 带错误处理
• SafeMapDirectSlice[From, To](from []From) ([]To, error) - 批量安全映射

🧪 Improvements

• 新增 Benchmark 测试用例
• 新增 example/func 使用示例

🔴 Breaking Changes

• 移除已废弃的 mapper_generic.go / mapper_generic_test.go
• 移除已废弃的 example/generic

Feature: Implement variable arguments based on NewMapper for flexible configuration settings when you init mapper

Version 0.7.14

• Feature: Implement variable arguments based on NewMapper for flexible configuration settings when you init mapper.
• Feature: Add Setting struct used to Config mapper
• you can use like this:

  // Default Setting:
  // EnabledTypeChecking:      false,
  // EnabledMapperStructField: true,
  // EnabledAutoTypeConvert:   true,
  // EnabledMapperTag:         true,
  // EnabledJsonTag:           true,
  // EnabledCustomTag:         false,
  // EnableFieldIgnoreTag:     false,
  
  /// When you use default setting
  NewMapper()
  
  /// When you will change some setting
  NewMapper(CTypeChecking(true), CCustomTagName("-"))

Full Changelog: v0.7.13...v0.7.14

Feature: Added the "composite-field" tag to mapping composite fields

Version 0.7.13

• Feature: Added the "composite-field" tag to continue expanding and searching for corresponding field mappings when encountering composite fields in a Struct. Currently, only one level of expansion is supported.
• Tips: Thanks to @naeemaei for issue #39
• For my birthday!
• you can use like this:

  // Base model
  type BaseModel struct {
      Id    int `json:"id"`
  }
  
  // Country model
  type Country struct {
      BaseModel `json:"composite-field"`
      Name      string `json:"name"`
  }
