full diff: https://github.com/imdario/mergo/compare/v0.3.7...v0.3.8

includes:

- imdario/mergo#112 Add strict override
    - fixes imdario/mergo#111 WithOverride should be able to check types
- imdario/mergo#106 Fix merging of interface types with concrete values
- imdario/mergo#120 should not overwrite pointers directly, instead check embedded values
    - fixes imdario/mergo#114 Embedded struct of pointer types will overwrite the whole destination struct
- imdario/mergo#125 added WithOverrideEmptySlice config flag
