Modification of the RSI indicator

Changes:

• Changed the number of dimensions (specifically to simplify use in experts)
• The line of the main indicator is composed of 4 with period shifts
• Added a line of smoothing based on T3 (I do not remember whose algorithm it is)
• The signals are moved to separate buffers
• Placed BB on T3 to improve the clarity of changes

Do not use it as a standalone trading tool, it is designed for confirmation of trend indicators.
