Added heap operations (#140 )

* Added support for using different malloc algorithms and implemented
ptmalloc commands

    - Added support for the mp_ structure from glibc
    - Fixed the bug when the base of [heap] is not sbrk_base (occurs
      when bss is very large).
    - Added an interface for interacting with ptmalloc heaps

* Added fastbins, unsortedbins, smallbins, largebins

    - Implemented the bin functions both in the ptmalloc interface in
      the heap/ directory and the commands function
    - Completed the bins command which prints all the commands
    - Added option to bin commands `verbose` specifies the users desire
      to print empty bins - linked lists with out any nodes from malloc
    - Changed bin representation to OrderedDict

* remove old bins command

* Ptmalloc bug fixes

    - switched constants.ptmalloc from using pwndbg.typeinfo to a gdb
      api function to prevent bugs when libc-dbg isn't installed
    - Other minor changes

* Added some functionality for when libc-dbg is not present

    - Added checks for finding symbols

* Ran isort on pwndbg

* Made few changes based on feedback from pull requests
    - Cleaned up spaces_table
    - Syntax changes

* Moved formatting code away from logic

    - Moved format_bin from pwndbg.heap.ptmalloc to pwndbg.commands.heap

* Fixed bug in spaces_table for 32 bit archs

* Changed malloc_chunk command to display FASTBIN instead of PREV_INUSE

    - Fixed local isort version problems

* Small bug fixes, tweaks, and added features list.

    - Changed pwndbg.chain.format to use the offset for the very last
      index in the chain.
    - Fixed bug with ptmalloc's main_arena property.
    - Added images to cap and links to FEATURES.md.
    - Changed bin commands to print hex instead of base 10.

* Modified docstring to match other docstrings in pwndbg

* Memoize properties, fix merge conflicst, fix constants

    - Moved the macros from the constants directory into the Heap
      class, left the constants there.
    - Switched from lazy loading to the memoize events.

* Fixed double spaces after images from a previous pull request.

* Added more examples to FEATURES.md for heaps

* Fix typos in FEATURES.md
