Version 2.0.0-alpha: Faster scans, improved UI and pattern detection

[BennyThadikaran]

Navigate charts using your keyboard. Press n key on the chart for next chart, p for previous and q to quit program.

Much faster scans using concurrent processing.

Now you can scan all patterns together or scan only bullish or bearish patterns.

User Interface

• Improved Charting with maximised screen use.
• On first run, prints useful configuration info.
• Save patterns in json file, plot patterns with --plot.
• Plot chart at particular index with --idx.

Faster Scans

• Improved scan speed using multiple processes and other minor
  improvements.
• Scan all patterns, or only bullish, or bearish patterns.

Improved Pattern detection and quality

• Fixed incorrectly formed patterns.
• Double Bottoms and Tops, uses ATR to limit pattern size across
  timeframes. This provides more tradeable patterns with better risk-reward.
• Eliminated triangles with widening slopes and extreme angles. Pennants are renamed to triangles.
• Tweaked shoulder height for Head & Shoulders. Horizontal entry line from right shoulder when slope of neckline is
  too exteme.
• Triangles futher identified as Symetric, Ascending, Descending in charts.
