Updates all occurrences of parsing/ToString-ing to use CultureInfo if
possible. This project can not reference QuantConnect.Common, so it's
unable to use the new StringExtensions.
See #3045
Adds static methods of the form Parse.<TypeName>(string str) that use
CultureInfo.InvariantCulture. These are to be used when parsing strings.
It's still safe (from the CA1304/CA1305 perspective) to use the ToDecimal
extension method for decimals.
Adds string extension methods for common operations that will now require
CultureInfo.InvariantCulture. These are to be used when converting values
to strings, such as ToStringInvariant()/ToStringInvariant(format), but also
useful for searching within strings, StartsWithInvariant, EndsWithInvariant
and IndexOfInvariant.
FxCop has various rulesets for enforcing things within our codebase.
For this particular issue, we'll be enforcing CA1304 and CA1305 to
ensure we're always using an IFormatProvider or a CultureInfo where
applicable.

This side steps the issue reported in #2840 by removing the desire to pass
zero for the maximum deviation. The previous issue was that we were leaning
on the trade ticks to produce the series variation and then trying to fit
quote ticks around a previously generated trade tick. This solution permits
both quote and trade ticks to produce variations and prevents the generator
from emitting both at the same time step.
A new parameter, --quote-trade-ratio, determines the relative density of each.
For example, a quote trade ratio of 1 means equal trade and quote ticks, whereas
a value of 2 means twice as many quote ticks as trade ticks.
This change also removes special treatment regarding the downsizing of the
requested deviation for quote ticks. If the consumer wants to limit the
deviation of quote ticks than the consumer can make that decision, but the
random value generator should simply follow instructions like a good little
boy.
Fixes#2840
Invoke from toolbox cli using --app=rdg or --app=randomdatagenerator
Produces random data over the requested time frame in the desired resolution,
security type and density.
Here's a few sample command line invocations:
--app=rdg --start=20190101 --end=20200101 --symbol-count=1 --resolution=Daily --data-density=Dense --include-coarse=false
--app=rdg --start=20190101 --end=20200101 --symbol-count=10 --security-type=Future --resolution=Hour --data-density=VerySparse
--app=rdg --start=20190101 --end=20200101 --symbol-count=5 --security-type=Option --resolution=Minute --data-density=Sparse
