v/vlib/encoding/base64/base64_test.v
Delyan Angelov 2d05c906d5 base64: some optimizations
* 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.
