Introduce new filter input stream with replacement facilities
-------------------------------------------------------------

                 Key: IO-218
                 URL: https://issues.apache.org/jira/browse/IO-218
             Project: Commons IO
          Issue Type: Improvement
          Components: Filters
    Affects Versions: 1.4
         Environment: all environments
            Reporter: Denis Zhdanov
             Fix For: 2.0, 1.4


It seems convenient to have a FilterInputStream that allows to apply predefined repalcement
rules against the read data. 
For example we may want to configure the following replacements:
{noformat}
{1, } -> {7, 8}
{1} -> {9}
{3, 2} -> {}
{noformat}
and apply them to the input like
{noformat}
{4, 3, 2, 1, 2, 1, 3}
{noformat}
in order to get a result like
{noformat}
{4, 7, 8, 9, 3}
{noformat}

I created the class that allows to do that and attached it to this ticket. Unit test class
at junit4 format is attached as well.

So, the task is to review the provided classes, consider if it's worth to add them to commons-io
distribution and perform the inclusion in the case of possible result.
