Updated miller to 5.2.0.

This release contains mostly feature requests.

Features:

    The stats1 verb now lets you use regular expressions to specify
    which field names to compute statistics on, and/or which to
    group by. Full details are here.

    The min and max DSL functions, and the min/max/percentile
    aggregators for the stats1 and merge-fields verbs, now support
    numeric as well as string field values. (For mixed string/numeric
    fields, numbers compare before strings.) This means in particular
    that order statistics -- min, max, and non-interpolated percentiles
    -- as well as mode, antimode, and count are now possible on
    string-only (or mixed) fields. (Of course, any operations
    requiring arithmetic on values, such as computing sums, averages,
    or interpolated percentiles, yield an error on string-valued
    input.)

    There is a new DSL function mapexcept which returns a copy of
    the argument with specified key(s), if any, unset. The motivating
    use-case is to split records to multiple filenames depending
    on particular field value, which is omitted from the output:
    mlr --from f.dat put 'tee > "/tmp/data-".$a, mapexcept($*, "a")'
    Likewise, mapselect returns a copy of the argument with only
    specified key(s), if any, set. This resolves #137.

    A new -u option for count-distinct allows unlashed counts for
    multiple field names. For example, with -f a,b and without -u,
    count-distinct computes counts for distinct pairs of a and b
    field values. With -f a,b and with -u, it computes counts for
    distinct a field values and counts for distinct b field values
    separately.

    If you build from source, you can now do ./configure without
    first doing autoreconf -fiv. This resolves #131.

    The UTF-8 BOM sequence 0xef 0xbb 0xbf is now automatically
    ignored from the start of CSV files. (The same is already done
    for JSON files.) This resolves #138.

    For put and filter with -S, program literals such as the 6 in
    $x = 6 were being parsed as strings. This is not sensible, since
    the -S option for put and filter is intended to suppress numeric
    conversion of record data, not program literals. To get string
    6 one may use $x = "6".

Documentation:

    A new cookbook example shows how to compute differences between
    successive queries, e.g. to find out what changed in time-varying
    data when you run and rerun a SQL query.

    Another new cookbook example shows how to compute interquartile
    ranges.

    A third new cookbook example shows how to compute weighted
    means.

Bugfixes:

    CRLF line-endings were not being correctly autodetected when
    I/O formats were specified using --c2j et al.

    Integer division by zero was causing a fatal runtime exception,
    rather than computing inf or nan as in the floating-point case.
