MemoryManager default options

[onionhammer]

Couple small issues here:

1. ".MemoryManger" is a typo, I assume, and should be "MemoryManager"
2. While it is now possible to override the options EPPlus uses, the documentation for RecyclableMemoryStream says the following

It is through these properties that you determine how large your pool can grow. If you set these to 0, you can have unbounded pool growth, which is essentially indistinguishable from a memory leak. For every application, you must determine through analysis and experimentation the appropriate balance between pool size and garbage collection.

Currently, if an EPPlus user does not manually override the "MemoryManger", and continually uploads larger and larger files, the default behavior of EPPlus will be to hold onto as much memory as at least as big as the biggest file processed.

Thanks for reporting this. We will correct the typo and have a look at the default behaviour.
