Mutable array support

[harendra-kumar]

Create a Streamly.Data.Array.Mut module for mutable arrays. This module will contain mutable APIs like writeIndex, and other range based writing APIs.

[harendra-kumar]

• Create Data.Array.Foreign.Mut module
• The import list in Streamly.Internal.Data.Array.Foreign has many mutable array module functions commented out, there may also be corresponding commented out code, move all these to new module
  • writeIndex etc.
  • partitionBy etc.
• Mutable array APIs: Many of the APIs from Streamly.Internal.Data.Array.Foreign.Mut.Type can be directly exported via Streamly.Internal.Data.Array.Foreign.Mut module.
• The mutable array APIs would have return type monadic instead of pure.
• Perhaps defaultChunkSize et al can be moved to some common IO module like Streamly.Internal.System.IO. It is used across many modules and it is not specific to arrays as such.
