Matrixprofile

- Added MPdist algorithm to compare two time series.
- Added `find_snippet()` that uses MPdist to show representative data.
- Added `mpx()` algorithm that doesn’t depends on FFT.
- Added `pmp()` pan-matrix profile.
- Improvement with several implementations in Rcpp. Computation speed
is much faster.
- Added `compute()`, `analyze()` and `visualize()`. Starting point in
the unified API from MPF.

- Changed `mass()` to `dist_profile()`, including options to different
algorithms.
- Added MASS\_V3 and MASS\_Weighted to `dist_profile()` algorithms.
- Function `dist_profile()` allows Query with Gap (QwG) and
Approximate Distance Profile (ADP, with PAA)
- Fixed long runtime of FFT for some data sizes, using MASS\_V3. Issue
\36.
- Added `stompi_update()` that updates the matrix profile allowing
real-time computation.
- Added `floss()` which can do real-time FLUSS computation.
- Added subset operator `[` for `tsmp` objects.
- Added `tail()` and `head()` for `tsmp` objects.
- Changed `find_motif()` for `MultiMatrixProfile` to report Motifs
correctly.

- Added `find_discord()` and its `print()` and `plot()` functions.
- Changed `plot()` for motifs to show where are the neighbors. Same
for discord.
- Added `valmod()` for Variable Length Motif Discovery.
- Changed `find_motif()` for compatibility with `valmod()`.

- Fixed `find_chains()` not returning the longest chain. Issue \33

- Fixed Matrix Profile print, dimensions are now reported correctly.
- Fixed pipe imports. Issue \22
- Fixed bug with `vars`. Issue \23
- Changed package license to GPL-3.
- Changed verbose mode, added one more step to separate messages from
progression bar.
- Fixed SCRIMP and added PRE-SCRIMP, so this is the SCRIMP++. AB-join
not yet implemented.
- Changed progress bar for a better one from `progress` package.
- Added Print and Plot to SiMPle. Issue \24
- Added Print and Plot to Salient.

IMPORTANT

- This version is a complete restructuration. The API has changed, and
the workflow is more friendly. This API is intended to be stable,
and from now on any change will pass through the “Deprecated” stage.

Added Features

- Outputs have a prettier print format.
- Outputs have a plot function. Try to plot a `tsmp()` output for
example.
- Now functions can work in `%>%` (pipe), e.g. `tsmp() %>%
find_motif()`. Except for SDTS that has a proper way to work.
- Added a wrapper function called `tsmp()` that handles the several
algorithms available.
- Added `as.*` functions to allow you to switch classes if you want,
e.g.: `as.matrixprofile()`.
- Changed all functions from dotted.case to snake\_case (except `as.*`
functions).
- Added Annotation Vectors.
- Fixed STOMP crash with Joins.
- Added support to query \< data in Joins.
- SCRIMP (experimental).
