Feature : Override Nil on merge

[VimalKumarS]

Request feature : override nil, if want to nullify dest with nil value

    dest:= make(map[string]interface{})
src :=make(map[string]interface{})

dest["col1"]=2
dest["col2"]=3
dest["col3"]=3
src["col1"]=nil
src["col2"]=4
src["col2"]=nil

mergo.Merge(&dest, src,mergo.WithOverride)

I tried to change code in order to set nil line#96

if srcElement.IsNil() {
			if (config.overwrite) {
				dst.SetMapIndex(key, srcElement)
				}
				continue
				}

thanks
Vimal

I was hoping that 128 PR resolve this issue, but no.

Need this too

@rusdevops Sorry, I wasn't able to do an early release. I'm working fixing 0.3.9 specific bugs and merging other PRs.

Reopening this issue as PR #105 introduced too many bugs, and this issue isn't fixed with the current state of master.
