CLI: Dump and replace support

[Miepee]

This PR adds the following functionality to the CLI:

• dump and replace individual code entries
• dump and replace all code entries
• dump all embedded textures
• replace all or individual embedded textures
• dump all strings

It does currently not add the functionality to the interactive menu. The only way right now to access these is via the parameters.

I can't get to work cli mass embed textures import after cli dump command working (using Win10x64).
To reproduce bug:

1. dump embed textures: "UndertaleModCli dump -t data.win"
2. import 'em back with: "UndertaleModCli replace -t UMT_REPLACE_ALL=./EmbeddedTextures -o temp.win data.win"
   Getting errors like:
   Data file does not contain an embedded texture named Texture 0.png!
   Data file does not contain an embedded texture named Texture 1.png!

If I'm doing import all emb textures in GUI it works (but after reneming "Texture 0.png" -> "0.png" and etc.) but in cli still not.
