* add new function headers
* new encoding function
* rename to decode_micro and add helper functions
* implement new decoding function
* add test for buffer to buffer decoding
* - add notice to GO code
- v fmt base64.v
* implement new decoding function
* fix base64_memory_test.v by commenting a few lines
* vfmt base64.v
* add some more asserts to base64_memory_test.v
* remove unused decoding function
* add bounds check, when detecting the padding
* use union for storing the decoded data

* Add a test for the base64 encoding/decoding of long strings (i.e. mainly memory allocation).
* Make vlib/encoding/base64/base64_memory_test.v resemble more test.v from https://github.com/kostya/benchmarks .
* base64: some optimizations, also add base64.encode_in_buffer and base64.decode_in_buffer .
* Fix tests passing static strings.
* Reduce time needed for base64_memory_test.v .
* Optimize encoding.base64.Index access too (it is static), which speeds up decoding.
