Add tests for checking boundary options in 1D convolution

3

This pull request intends to add unit tests for verifying boundary manipulation in `1D convolution`. Since these are tests(used for proving `correctness` of implementation), I have favoured readability/simplicity over performance(for...

kernel_2d_fixed giving false assertion errors

### Actual behavior ``` boost::gil::detail::kernel_2d_fixed ``` gives false assertion errors during its initialization. ### Expected behavior A 2D kernel with provided values and center co-ordinates should be created ### C++...

Port TuttleOFX extension : aligned

### Description This pull request intends to port ```aligned``` extension from [TuttleOFX repository](https://github.com/tuttleofx/TuttleOFX/tree/develop/libraries/boostHack/boost/gil/extension/toolbox) to Gil as mentioned in #449 . I have tried not to change anything significant in actual...

```Reflection``` option for boundary handling is currently not available in 1D correlation. It is a common feature available in other standard libraries.

Add separate implementation for `2D correlation` which would facilitate its standalone use as well. # Resources referred - https://github.com/selbyk/colors_in_image/blob/9586f86b46f5db28c13071119973dc3a62d24b9c/main.cpp#L291

Provide different options for handling boundary pixels during` 2D convolution`. # Resources referred - [A Functional Approach to Border Handling in Image Processing](http://web.science.mq.edu.au/~len/preprint/hamey-dicta2015-functional-border.pdf)

Improve kernel generation for Sobel operator
